===Early years===
[[File:David_Dunbar_Buick.jpg|thumb|left|150px|David Buick, founder of the Buick Motor Company]]
Buick is one of the oldest automobile brands in the world and is currently the oldest in the United States still active today. [[Autocar Company|Autocar]], founded in 1897, is the oldest motor vehicle manufacturer in the [[western hemisphere]]; while originally an automobile maker, Autocar now builds heavy trucks. [[Oldsmobile]], also an early automaker founded in 1897, is now defunct; [[Studebaker]] was founded in 1852, but did not begin producing automobiles until 1902; [[Henry Ford]] produced his first car in 1896 but did not start the [[Ford Motor Company]] until 1903, and during the period in between was involved with other automobile manufacturers such as [[Cadillac]], founded in 1902.

The first two Buick automobiles were made in 1899 and 1900 at the "Buick Auto-Vim and Power Company" by chief engineer [[Walter Lorenzo Marr|Walter Marr]],<ref name="The Buick 1987"/> but company owner [[David Dunbar Buick]] was reluctant to begin making automobiles, being satisfied with stationary and marine engine production, so Marr left Buick in 1901 to found [[Marr (automobile)|his own automobile company]] under his own name. His replacement was Eugene Richard, who applied for a patent in 1902 for Marr's valve-in-head ([[Overhead valve engine|overhead valve]]) engine, which patent, number 771,095, was awarded to Richard in the name of Buick in 1904.<ref name="The Buick 1987"/> In 1903, the third Buick automobile was made, this time by Richard, but in 1904 Buick, whose company was now called "Buick Motor Company", moved from Detroit to Flint, Michigan, and Richard stayed behind. Marr was rehired in Flint as chief engineer, to begin making automobiles in production. That year, 37 Buick automobiles were made, production increasing to 750 in 1905, 1,400 in 1906, 4,641 in 1907, and 8,820 in 1908, taking the number one spot away from close competitors [[Ford Motor Company|Ford]], [[Maxwell automobile|Maxwell]] and [[Oldsmobile|Olds Motor Works]].<ref name="The Buick 1987"/> Buick proclaimed themselves the largest car manufacturer in the world this year.<ref>{{cite magazine | ref = GJ91 | title = Buick - mannen och bilen | trans-title = Buick - the man and the car | language = sv | magazine = [[Teknikens Värld]] | publisher = Specialtidningsförlaget AB | location = Stockholm, Sweden | page = 40 | date = 1991-07-18 | issue = 14 | volume = 43 | first = George | last = Johansson }}</ref>

David Buick incorporated his company as the Buick Motor Company on May 19, 1903, in [[Detroit]], Michigan. Buick had been financed by a friend and fellow automobile enthusiast, [[Benjamin Briscoe]], who in September 1903 sold control of the business to [[James H. Whiting]], of [[Flint Wagon Works]], in [[Flint, Michigan]].<ref>{{cite web|url= http://www.flint.lib.mi.us/timeline/autohistory_0798/whitingJ.html |title=James H.

The engine Buick and Marr developed for this automobile was a two-cylinder valve-in-head engine of 159 cubic inches, with each cylinder [[boxer engine|horizontal and opposed to the other by 180 degrees]].

Whiting built only a few automobiles in 1904, the [[Buick Model B|Model B]], before running out of operating capital, causing him to bring in [[William C. Durant]] that year as a controlling investor. Durant built a few more model B's in 1904, stepped up production for the model C in 1905, and spent the next four years turning Buick into the biggest-selling automobile brand in the US.

During the 19th century, Durant had made his fortune as co-owner, also in Flint, with [[Josiah Dallas Dort]], of the [[Durant-Dort Carriage Company]], which by 1904 was the largest carriage-making company in the country and one of the largest in the world.<ref name="The Buick 1987"/> Durant moved most Buick production to the former Durant-Dort Imperial Wheel plant in [[Jackson, Michigan]] in 1905. Buick continued car production in Jackson through 1907, when Factory #1 was completed in Flint. The Jackson plant continued production with Buick trucks through 1912.<ref>{{cite web|url= http://buickcity.blogspot.com |title=All Things Buick |website=buickcity.blogspot.com |access-date=2018-07-09}}</ref> David Buick sold his stock upon departure in 1906, making him a wealthy man, but he died in modest circumstances 25 years later. In 1907, Durant agreed to supply motors to [[Samuel McLaughlin|R. S. McLaughlin]] in Canada, an automaker, and in 1908 he founded [[General Motors]].

Between 1899 and 1902, two prototype vehicles were built<ref>{{cite web |url= http://www.welovebuicks.com/history.html |title=Buick History |website=welovebuicks.com |access-date=2010-10-16 |archive-url= https://web.archive.org/web/20090307002136/http://www.welovebuicks.com/history.html |archive-date=2009-03-07 |url-status=dead }}</ref> in Detroit, Michigan by [[Walter Lorenzo Marr]]. Some documentation exists of the 1901 or 1902 prototype with [[tiller]] steering<ref>{{cite web |url=http://www.prewarbuick.com/cars/19/1901-Buick-perhaps-1902 |title=1901 Buick perhaps 1902 |website=prewarbuick.com |date=2002-01-01 |access-date=2010-10-16 |archive-date=2020-08-11 |archive-url=https://web.archive.org/web/20200811002904/http://www.prewarbuick.com/cars/19/1901-Buick-perhaps-1902 |url-status=dead }}</ref> similar to the [[Oldsmobile Curved Dash]].

In mid-1904, another prototype was constructed for an endurance run, which convinced Whiting to authorize the production of the first models offered to the public.<ref>{{cite web |url= http://thewhiting.com/aboutus/history.html |title=James H. Whiting |website=thewhiting.com |access-date=2010-10-16 |archive-url= https://web.archive.org/web/20100522235557/http://thewhiting.com/aboutus/history.html |archive-date=2010-05-22 |url-status=dead }}</ref> The architecture of this prototype was the basis for the Model B.

The first Buick made for sale, the 1904 horizontally opposed 2-cylinder engine [[Buick Model B|Model B]], was built in Flint, Michigan at a re-purposed factory that was known as the [[Flint Wagon Works]]. There were 37 Buicks made that year, none of which survive. There are, however, two replicas in existence: the 1904 endurance car, at the Buick Gallery & Research Center in Flint, and a Model B assembled by an enthusiast in California for the division's 100th anniversary.<ref>{{cite web |url= http://1929buick.com/gallery/sloan |title=1904 Buick Prototype - Sloan Museum |website=1929buick.com |access-date=2010-10-16 |archive-url= https://web.archive.org/web/20110707060319/http://1929buick.com/gallery/sloan |archive-date=2011-07-07 |url-status=dead }}</ref><ref>{{cite web |url= http://1929buick.com/gallery/1904buick |title=1904 Buick Model B - Restoration Project |website=1929buick.com |access-date=2010-10-16 |archive-url= https://web.archive.org/web/20110707060327/http://1929buick.com/gallery/1904buick |archive-date=2011-07-07 |url-status=dead }}</ref> Both of these vehicles use various parts from Buicks of that early era, as well as fabricated parts. These vehicles were each constructed with the two known surviving 1904 engines.

The early success of Buick is attributed mainly to what it called the valve-in-head engine, now known as the [[Overhead valve engine|overhead valve]] (OHV), engine<ref>{{cite web |url= http://www.buick.com/heritage/index.jsp |title=A Heritage of Precision |publisher=Buick |access-date=2010-10-16 |archive-url= https://web.archive.org/web/20080923214212/http://www.buick.com/heritage/index.jsp |archive-date=2008-09-23 |url-status=dead }}</ref> patented by Eugene Richard and developed by Richard, Buick, and Marr.

The Model F was similar to the Model G, a lower-priced two-seat roadster, produced from 1906 until 1909. Both the F and G were powered by a {{convert|159|CID|L|1|abbr=on}} two-cylinder 159 engine producing {{convert|22|hp|kW PS|0|abbr=on}} along with a 2-speed transmission as well as mechanical brakes on the rear wheels.

The [[flat-twin]] engine is inherently balanced, with [[torque]] presented to the chassis in a longitudinal manner. The engine was mounted [[Mid-engine design|amidships]].<ref>{{cite web |url= http://1929buick.com/gallery/history/aag |title=Buick History (1904-1929) |website=1929buick.com |access-date=2010-10-16 |archive-url= https://web.archive.org/web/20110707060331/http://1929buick.com/gallery/history/aag |archive-date=2011-07-07 |url-status=dead }}</ref>

[[William C. Durant|Billy Durant]] was a promoter, and Buick soon became the largest carmaker in America. Durant embarked on a series of corporate acquisitions, calling the new firm [[General Motors]]. At first, the manufacturers comprising General Motors competed against each other, but Durant ended that. He wanted each General Motors division to target one class of buyers. Buick was positioned below the [[Cadillac (automobile)|Cadillac]] brand. To save on resources, Buick vehicles shared a common platform, called the [[GM A platform]], that was shared with [[Chevrolet]], [[Oakland Motor Car Company|Oakland]], [[Oldsmobile]], and Cadillac.

At first, Buick followed the likes of [[D. Napier & Son|Napier]] in [[automobile racing]], winning the first-ever race held at [[Indianapolis Motor Speedway]].<ref>Wells, Dick. "SRMA Update" in ''Street Rodder'', 12/98, p.298. The accuracy of this source is in question, however.</ref>

The first full-size Buick to join the smaller Model B was in 1907, when the [[Buick Four|Buick Model D]] was introduced with a four-cylinder {{convert|4178|cc|cid|1|abbr=on|order=flip}} T-head engine, installed in the front with rear-wheel drive. This was one of the only cars with side valves that Buick ever made.<ref>{{cite web|url= http://www.carnut.com/specs/gen/buick20.html|archive-url= https://web.archive.org/web/20190226060957/http://www.carnut.com/specs/gen/buick20.html |url-status=dead|archive-date=2019-02-26|title=Buick Pre 1930 General Specs |website=carnut.com}}</ref>

====1910s–1920s====
[[File:Louis Chevrolet in Buick Bug 1910.jpg|thumb|[[Louis Chevrolet]] in his [[Buick 60 Special]] (aka "Buick Bug") in 1910]]

In 1910, Buick introduced the [[Buick Four|Model 10]] with an OHV four-cylinder engine<ref>{{cite web |title=1910 Buick Model 10 |url= https://www.bonhams.com/auctions/20994/lot/129/?category=list |work=Bonhams |access-date=19 December 2020}}</ref> followed in 1911, with their first closed-body car, the [[Buick Six]],<ref>Clymer, Floyd. ''Treasury of Early American Automobiles, 1877-1925'' (New York: Bonanza Books, 1950)</ref> that followed the same bodystyle that first appeared at Cadillac, and four years ahead of [[Ford Motor Company|Ford]]. The car was built at the all-new factory in Flint which later became known as [[Buick City]].<ref>Clymer, p.120.</ref> Buick during the 1920s made various sized vehicles, with series designations for different years, sometimes using numbers, while later years using lettered designations. One of the larger vehicles, with a straight-six, was the [[Buick Master Six]]. The Model 10 was phased out during a restructuring initiated by GM's new leadership that assumed position on November 15, 1910.<ref>{{Cite book |last=Gustin |first=Lawrence R. |title=Billy Durant: Creator of General Motors |publisher=University of Michigan Press |year=2008 |isbn=978-0-472-03302-7 |location=Ann Arbor, Michigan |pages=142 |language=en}}</ref>

In the 1910s and 1920s, Buick was a prestige brand in the Republic of China with the brand driven by or for high-level politicians and the [[Emperor of China|Emperor]]. The latter imported two Buick cars in 1924, making it the first automobile to enter China.<ref name=":0" /> By 1930, Buick claimed one-sixth of the total number of cars in the country.<ref name=":0">{{Cite book |last1=Nordhielm |first1=Christie L. |title=Marketing Management: The Big Picture |last2=Baron |first2=Marta Dapena |publisher=John Wiley & Sons |year=2015 |isbn=978-1-118-01455-4 |location=Hoboken, NJ |pages=199 |language=en}}</ref> Buick now sells 80% of its production in the People's Republic of China and is a minor player in Taiwan.<ref>{{cite web|url= https://money.cnn.com/2017/02/22/news/companies/buick-china-history-brand/index.html |title=Buick is a lot more than a dad wagon in China |website=money.cnn.com |date=22 February 2017}}</ref>

In 1929, as part of [[General Motors Companion Make Program|General Motors' companion make program]], Buick Motor Division launched the [[Marquette automobile|Marquette]] sister brand, designed to bridge the price gap between Buick and [[Oldsmobile]]. Its styling featured a high peaked hood and radiator shell while its suspension used four, parallel, semi-elliptical springs with [[Remy International|Delco-Lovejoy]] shock absorbers.<ref>{{Cite book |last=Kollins |first=Michael J. |title=The Big Three |publisher=SAE International |year=2002 |isbn=0-7680-0900-6 |pages=136 |language=en}}</ref> Marquette was discontinued in 1930. All Buick, Marquette, [[Viking (automobile)|Viking]], and Oldsmobile products shared the newly introduced [[GM B platform]] starting in 1926.

====1930s====
Buick debuted two major achievements for the 1931 model year, the [[Overhead valve|OHV]] [[Buick Straight-8 engine]] and a [[synchromesh transmission]] in all models but the Series 50. The Eight was offered in three displacements, the 220 cubic inch (bore 2 7/8 in. stroke 4.25 in.), was available in the Series 50 with 77 brake HP. The Series 60 engine was a 272 cu. in. unit (bore 3 1/16 in., stroke 5 in.) giving 90 brake HP. Cadillac had previously introduced the [[Cadillac Type 51]] with a flathead V8 engine in 1915 which made usage of an eight-cylinder engine a luxury feature.

The Series 80 and Series 90 used a 344 cu. in. version (bore 3 5/16 in., stroke 5 in.) for 104 brake HP. Automatic vacuum-operated spark advance was another feature replacing the steering column-mounted spark lever although an emergency lever was now dash mounted. Buick scored another first in 1939 when it became the first company to introduce [[turn signal]]s, which did not appear on other car brands until almost a decade later.<ref>{{cite news|url= https://www.nytimes.com/2013/07/14/magazine/who-made-that-turn-signal.html?_r=0 |title=Who Made That Turn Signal? |date=July 12, 2013 |newspaper=The New York Times}}</ref> All 1939 models also had a steering column-mounted shift lever.

In the mid-1930s McLaughlin-Buicks were purchased by British monarch [[Edward VIII]].<ref>{{cite news|url= https://www.telegraph.co.uk/news/uknews/1338217/Car-that-took-King-into-exile-goes-on-sale.html |location=London |work=The Daily Telegraph |first=Caroline |last=Davies |title=Car that took King into exile goes on sale |date=2001-08-23}}</ref> He had a preference for the Canadian built McLaughlin-Buick.<ref name="vancetimescolonist">{{cite news |last1=Vance |first1=Bill |title=Ontario car company became GM Canada |url= https://www.timescolonist.com/driving/bill-vance-ontario-car-company-became-gm-canada-4672987 |newspaper=Victoria Times Colonist |date=May 24, 2019 |access-date=April 28, 2022}}</ref> Buicks were used for royal transport within Canada, including for King [[George VI]] and Queen [[Elizabeth Bowes-Lyon|Elizabeth]] during the [[1939 royal tour of Canada]].<ref name="vancetimescolonist"/>

In the 1920s and 1930s Cadillac and Buick vehicles were popular with long-distance passenger service operators e.g. the [[Nairn Transport Company#Vehicles|Nairn Transport Company]] in the Middle East (Baghdad-Damascus).

[[File:1910-buick-archives.jpg|thumb|1910 Buick Bug race car and 1944 M18 Buick Hellcat tank destroyer]]

1940 saw the first use of the "[[Buick Estate|Estate]]" designation for Buick on the [[Buick Super|Super]] station wagon. World War II stopped automobile production in 1942. Starting that year, Buick produced the [[M18 Hellcat]] tank destroyer and supplied radial engines for the [[Consolidated B-24 Liberator|B-24 Liberator]], [[Douglas C-47 Skytrain]], and [[Douglas C-54 Skymaster]]. By the fall of 1945, automobile production resumed. In 1948, the [[Dynaflow]] automatic transmission was first offered by Buick. 1949 saw the debut of Buick's [[#VentiPorts|VentiPorts]].

====1950s====
1953 marked Buick's 50th anniversary as well as the introductions of the [[Buick V8 engine]] and the Roadmaster Skylark. In 1955, Buick had its best model year sales to date with 738,814 vehicles sold; a record that would hold until 1977. In 1957, Buick's new 364 cu. in. engine block and [[ball joint]] front suspension debuted and Roadmasters now had [[aluminum]] finned brake drums. 1959 saw the introduction of three new models: [[Buick Electra|Electra]], [[Buick Invicta|Invicta]] and [[Buick LeSabre|LeSabre]] as well as a new 401 cu. in. V8 engine in the Electra and Invicta. An Electra also paced the [[Indianapolis 500]] race that year.

====1960s====
An Electra 225 paced the [[Daytona 500]] race in both 1960 and 1963. In 1961, a new [[Fireball V6]] engine was introduced and the [[Buick Skylark|Skylark]] nameplate returned as the top model of the new [[Buick Special|Special]] compact car line. The Buick Special was named [[Motor Trend Car of the Year]] in 1962. Also in 1962, [[Buick Wildcat|Wildcat]] was introduced as a trim level on Invicta and became its own model the following year. In 1963 the [[Buick Riviera|Riviera]] was introduced as its own model. In the mid-1960s Buick started officially selling German-built [[Opel]] cars through its North American dealerships. For 1967, [[radial tire]]s became available as an option on all full-size Buicks.<ref>LaChance, David (July 2006).

====1970s====
The 1970s saw a number of new models added to the Buick lineup including the Estate Wagon as its own model in 1970, [[Buick Centurion|Centurion]] in 1971, [[Buick Apollo|Apollo]] in 1973, and [[Buick Skyhawk|Skyhawk]] in 1975. 1975 also saw the first appearance of the "[[Buick Park Avenue|Park Avenue]]" nameplate for Buick as a trim/option package on the Electra 225 Limited. A Buick Century paced the Indianapolis 500 race not once but twice in the mid-1970s. In 1976, Buick began selling rebadged [[Isuzu Gemini]]s as Opels to replace the Opel Kadett models it had previously marketed. The following year, Electra 225 and LeSabre were redesigned and downsized, and the Buick brand saw its best model year sales to date with 773,313 vehicles sold. 1978 marked Buick's 75th anniversary and welcomed a redesigned Century as well as a redesigned Regal coupe which was now available with a turbocharged [[Buick V6 engine|V6]] engine. Buick model year sales broke another record in 1978 with 795,316 vehicles sold. In 1979, the Riviera was redesigned; Riviera S-Type was named Motor Trend Car of the Year.

====1980s====
In the 1980s, Buick's lineup saw several changes including the downsizing of various models. In 1980, Lloyd Reuss was appointed as general manager and further pushed Buick into turbocharging, racing, and performance production cars, building momentum which continued a number of years after his departure in 1984 as he headed toward a brief term as GM president. Also in 1980, the [[Oldsmobile Diesel engine|Diesel engine]] became available on select Buick models and Somerset was introduced as an optional package on the Regal Limited. In 1981, the [[T-Type]] performance trim was introduced on the Riviera. Regal was the official pace car of the [[Indianapolis 500]] race in 1981. In 1982, the [[Buick Grand National|Grand National]] high-performance package was first offered on Regal. A soft-top Riviera helped lead the return of the convertible, which had disappeared from domestic lineups in 1976. The following year, a Riviera convertible with a twin-turbo V6 paced the Indy 500. Also in 1983, Buick had its best model year to date with 810,435 vehicles sold.

In 1984, Buick was the official car of the [[1984 Summer Olympics|XXIII Olympiad]]. A reorganization split manufacturing & engineering from sales and marketing. The first pilot Buick is produced at "Buick City", a state-of-the-art assembly center built inside the walls of Buick's home plant in Flint. Buick had its best model year sales to date with 906,626 vehicles sold plus Buick's worldwide sales topped one million for the first time. Lloyd Reuss ended his tenure as general manager of the Buick Motor Division in 1984.

For the 1985 model year, Buick introduced the downsized sixth-generation Electra, effectively GM's first front-drive, transverse-engine, full-size unibody cars &mdash; initially powered by a carbureted 3.0 liter Buick [[V6 engine]], a fuel-injected 3.8 liter Buick V6 engine, or a 4.3 liter [[Oldsmobile Diesel engine|Oldsmobile diesel]] V6 engine. Each was mated to a 4-speed [[automatic transmission]] with a 0.70:1 overdrive gear. The 3.0 liter V6 and 4.3-liter diesel V6 were discontinued after 1985. During the 1985 through 1989 model years, the Electra name also continued to be used on the rear-wheel-drive B-body "Estate" station wagon. Also in 1985, Buick introduced the [[Buick Somerset|Somerset]] as its own model. Buick-powered cars won the pole and second position in qualifying for Indianapolis 500. Over the next few years, Buick engines would set a number of stock-block records and twice would power a third or more of the 33-car Indy 500 field (11 in 1990 and 12 in 1992). 1985 would be the final year for the rear-drive LeSabre before another downsizing and conversion to front-wheel-drive for 1986 (sedans and coupes only; the rear-drive LeSabre Estate Wagon would soldier on largely unchanged for a few more years). The top-line LeSabre Limited became the LeSabre Limited Collectors Edition to mark the end of an era for the rear-wheel-drive coupe and sedan; engine offerings included the standard 231 V6 (sedans and coupes) or optional Olds 307 V8 or Oldsmobile 350 diesel V8. 1985 saw Buick's best model year sales to date with 915,336 vehicles sold.

In 1986, the LeSabre was introduced on the new [[front wheel drive]] [[GM H platform|H platform]], after departing from [[rear wheel drive]] on the [[GM B platform]]. Joining the LeSabre on the H-body included the [[Oldsmobile 88|Oldsmobile Delta 88]]. Like the previously introduced Electra, the LeSabre's hood was hinged at the front of the car instead of near the cowl and windshield. Styling and did not include Buick's long-standing [[#Ventiport|ventiports]] or [[#Sweepspear|sweepspear]] styling cues. In 1986, a LeSabre Grand National model was built to qualify the coupe body style for NASCAR competition. Less than 120 units were made, all finished in black with a gray interior.<ref>{{cite web|url= http://lesabret-type.com/LeSabreGN.html |title=1986 LeSabre Grand National Page |access-date=2012-01-08 |url-status=dead|archive-url= https://web.archive.org/web/20120211083727/http://lesabret-type.com/LeSabreGN.html |archive-date=2012-02-11}}</ref>

Also for 1986, the [[GM E platform|E-body]] Riviera was converted to [[Monocoque|unibody construction]] and further downsized to a {{convert|108|in|mm|abbr=on}} wheelbase similar in length to that of the [[Buick Regal]]. The V6 was now the only engine, rated initially at {{Convert|142|hp|kW|0|abbr=on}} SAE and {{convert|200|lbft|Nm|-1|abbr=on}} of torque. It used the Turbo-[[Hydramatic]] 440-T4 [[Automatic transmission|automatic]] with a 2.84:1 final drive ratio. This generation was noted for advanced electronic instrumentation displayed on a dash-mounted {{convert|9|in|mm|adj=on}} CRT. The CRT controlled the vehicle's climate control system and stereo, and also supplied advanced instrumentation such as a [[trip computer]] and maintenance reminder feature. Four-wheel disc brakes were standard. With a choice of three suspension packages available, up to the performance oriented FE3 setting, handling was notably improved. The Riviera placed fourth for ''[[Motor Trend]]''{{'}}s 1986 Car of the Year contest. Fuel economy was notably improved for the 1986 Riviera, but the investment in the downsized, [[transverse engine]] front-wheel drive platform resulted in a substantial price increase to $19,831 for the base model to $21,577 for the new [[T-Type]]. Downsizing also resulted in a dimensional similarity to smaller, less expensive offerings from GM. The smaller dimensions, generic styling, and lack of a V8 led to Riviera sales plummeting to 22,138 for 1986.

In 1987, the last of the turbo/intercooled Regal Grand Nationals, often called the quickest American cars, were offered as well as 547 even quicker special edition '87 GNXs. It would also be the last year for the rear-wheel-drive Regal. General manager Ed Mertz promoted the new "Premium American Motorcars" theme which focused Buick marketing on the various qualities that made the marque famous.

In 1988, Buick was the official car of the [[U.S. Olympic Team]]. The [[Buick Reatta|Reatta]] two-seater was introduced, to be followed two years later by a convertible. Also in 1988, [[Buick Regal|Regal]] was downsized and converted to front-wheel drive. Bobby Allison won the Daytona 500 in a Regal that year. 1988 also saw the debut of the slogan "The Great American Road Belongs to Buick".

In 1989, a new Electra trim level was offered called the Park Avenue Ultra. The Ultra was an upgrade to the Electra Park Avenue and featured a standard leather-trimmed interior with dual 20-way power front seats (shared with Cadillac's restyled 1989 [[Cadillac Sixty Special|Fleetwood Sixty Special]]), lower-body accent exterior paint treatment, distinctive thick-padded vinyl top with limousine-style rear-window surround (available only on Ultra), simulated burled elm trim on the doors and instrument panel, unique aluminum wheels, anti-lock brakes, chromed [[B-pillar]] moldings, specific grille and tail lamps, leather-wrapped steering wheel, electronic instrumentation, padded glove-compartment door, unique interior door panel trim, and a variety of otherwise minor changes. With its long list of standard equipment, the Park Avenue Ultra carried a higher base price than Cadillac's [[Cadillac de Ville series|Sedan de Ville]]. The Riviera was also restyled for 1989, adding 11 inches to its overall length. In the late 1980s, the Flint-built LeSabre ranked #1 in North America and #2 in the world in a major independent quality study which eventually led Buick to change its ad slogan from "The Great American Road Belongs to Buick" to "Buick: The New Symbol for Quality in America."

====1990s====
In 1990, the first Reatta convertible was produced. 1990 was also the last year for the Electra as Park Avenue, previously a trim level on the Electra, became its own model for the 1991 model year. In 1991, Buick led the industry in improvement in sales and market share. A new four-door Regal came to market for 1991, the first Regal sedan since 1984. Buick also introduced a supercharged 3.8-liter V6 in the Park Avenue Ultra. Supercharging became so popular at Buick that by the new millennium, Buick was the leading marketer and industry leader of supercharged cars. 1991 saw the return of the [[Buick Roadmaster|Roadmaster]] after a 33-year absence. The Roadmaster was first offered as a wagon only and then a sedan was added for 1992.

For 1992, the popular LeSabre was redesigned along the same lines as the previous year's [[Buick Park Avenue|Park Avenue]]. 1992 also saw the introduction of a new, redesigned Skylark. In 1993, a special edition LeSabre was sold to commemorate Buick's 90th anniversary. In addition to Custom trim level standard equipment, included were "90th Anniversary" badging, cassette player, cruise control, rear-window defogger, power driver's seat, carpeted floor mats, exterior pinstripes, and choice of wire or aluminum wheel covers.

In 1995, after a hiatus in 1994, the Riviera returned with radical styling that departed from the previous generations' more traditional image. A {{convert|205|hp|abbr=on}} [[naturally aspirated]] 3800 V6 was standard, with a [[supercharger|supercharged]] version rated at {{Convert|225|hp|kW|0|abbr=on}} and {{Convert|275|lbft|Nm|0|abbr=on}} available as an option. Rivieras were now assembled in [[Lake Orion, Michigan]], riding the same Cadillac-derived [[GM G platform (FWD)|G platform]] as the 4-door [[Oldsmobile Aurora]].

In 1996, both the Roadmaster sedan and wagon were discontinued. In 1998, after 95 years in Flint, Buick's headquarters was moved to Detroit. Bob Coletta, Buick general manager, saw the first Chinese Buick roll off the line at Shanghai before he turned over the top Buick job to Roger Adams. Buick Gallery and Research Center opened at Flint's Sloan Museum. A reorganization of the division split sales from marketing.

In 1999, the last of nearly 16 million Buicks were built in Flint's Buick City. The last car, a 1999 LeSabre, rolled off the assembly line on June 29 that year. In a major independent quality study, Buick ranked #2 (and top domestic) among 37 international brands and Buick City shared the top world position among automotive assembly plants. With sales of all coupes declining in the North American market, GM decided to discontinue the Riviera. 1999 was the car's last model year with production ceasing on November 25, 1998. The final 200 cars had special silver paint and trim and were denoted "Silver Arrow"<ref>{{cite web|url= http://www.rivowners.org/silver.html|title=Riviera Owners Association}}</ref> models, a designation which hearkened back to several Silver Arrow show cars that had been built off Riviera bodies by [[Bill Mitchell (designer)|Bill Mitchell]]. The eighth generation Rivieras received the most powerful V6 Buick engine since the [[Buick Grand National|Grand Nationals]] of the 1980s. The supercharged [[Overhead valve|OHV]] V6 gave impressive [[torque]] and acceleration, pushing the car from 0 to {{convert|60|mph|km/h}} in under 7 seconds, and turning the {{frac|1|4}} mile in 15.5 seconds and achieved MPG fuel efficiency ratings of 18 city/27 highway.

====2000s====
In the 2000s, Buick's lineup was modified with the compact and performance segments being abandoned in favor of the crossover/SUV market which was growing in popularity. In 2000, Buick headed into the new millennium with a redesigned LeSabre (best-selling U.S. full-size car for eight straight years) and a more powerful Century. Since the first Detroit experimental car of 1899–1900 and the first Flint production car of 1904, more than 35 million Buicks had been built. The 2000 LeSabre was introduced in March 1999 and was now built on [[General Motors|GM's]] [[GM G platform (FWD)|G platform]]; however, GM chose to continue to refer to it as the H platform.<ref name="Frame">{{cite web|last=Frame|first=Phil|title=GM H Cars Move to G Platform |url= http://www.autonews.com/apps/pbcs.dll/article?AID=/19950116/ANA/501160730#axzz2TYYYR1jT |work=Automotive News |access-date=17 May 2013 |archive-url= https://archive.today/20130616065939/http://www.autonews.com/apps/pbcs.dll/article?AID=/19950116/ANA/501160730%23axzz2TYYYR1jT |archive-date=16 June 2013|url-status=dead|date=16 January 1995}}</ref> The LeSabre was manufactured at GM's [[Detroit/Hamtramck Assembly]] factory in [[Hamtramck, Michigan]] and Lake Orion Assembly, in Lake Orion, Michigan. Some of the changes with the redesign included a new grille that did not open with the hood and slightly smaller exterior dimensions. Despite its somewhat smaller exterior size, it still offered similar interior room and more trunk space than the previous model. 2001 saw Buick's first entry into the crossover market with the introduction of the [[Buick Rendezvous|Rendezvous]] as a 2002 model. In 2003, the [[Buick Centieme]] crossover [[concept car]] commemorated Buick Motor Division's 100th anniversary. Some of the Centieme's exterior design and interior features would later appear on the 2008 [[Buick Enclave|Enclave]] crossover. In 2004, Buick added the [[Buick Rainier|Rainier]] mid-size SUV, and the new [[Buick Terraza|Terraza]] minivan was added a year later.

In the years following, Buick began consolidating its North American lineup and by 2008 had reduced it to just three models: the [[Buick LaCrosse|LaCrosse]]/Allure, the [[Buick Lucerne|Lucerne]], and the new-for-2008 Enclave. The Super name had also returned after a 50-year absence as a new performance trim level on LaCrosse and Lucerne. The brand's total overall sales slipped in the United States, and, with a reputation for primarily appealing to older buyers, rumors circulated throughout this decade that the Buick marque would be discontinued.<ref>{{cite web| url= http://www.thetruthaboutcars.com/buick-and-the-detroit-zombies/ |title=Buick and the Detroit Zombies |first=Andrew |last=Dederer |work=The Truth About Cars |date=2008-04-25 |access-date=2011-09-23 }}</ref> The profitability of the model lineup and popularity in China ensured Buick's future within General Motors, with the decision being made to discontinue the [[Pontiac (automobile)|Pontiac]] brand instead.<ref>{{cite web|url= http://www.autoobserver.com/2009/06/good-gm-maybe-not-all-that-good.html |title='Good' GM: Maybe Not All That Good |last=Krebs |first=Michelle |publisher=Edmunds Auto Observer |date=2009-06-29 |access-date=2011-06-03}}</ref>

Since 2005, GM had gradually consolidated Buick with [[GMC (automobile manufacturer)|GMC]] and former [[Pontiac (automobile)|Pontiac]] dealerships to create the current Buick-GMC network. During [[General Motors Chapter 11 reorganization]] and emergence in 2009, the company designated Buick as a "core brand", citing the division's success in China.<ref>{{cite web|url= http://wot.motortrend.com/gm-ceo-henderson-says-buick-is-a-core-brand-uaw-talks-could-reopen-if-need-be-4343.html |title=GM CEO Henderson Says Buick is a Core Brand |last=Evans |first=Scott |website=MotorTrend.com |date=2009-04-02 |access-date=2011-06-03}}</ref> Behind the scenes, GM began to move products originally planned for other brands to Buick.

====2010s====
The 2010s included the return of a classic Buick nameplate, the [[Buick Regal]], and several new model names. The decade also saw the brand's first hatchback since 1987, its first factory convertible since 1991, and its first station wagon since 1996. Buick further expanded its presence in the popular crossover/SUV market in the 2010s.

In January 2009, Buick unveiled the new 2010 LaCrosse sedan, an all-new styling direction that included traditional Buick cues. The market responded positively to the LaCrosse and reviews favorably compared it to luxury models such as the [[Lexus ES]].<ref>{{cite web |url= http://www.motortrend.com/roadtests/sedans/112_1004_2010_buick_lacrosse_2010_lexus_es_350_comparison/results.html |title=Comparison: 2010 Buick LaCrosse CXS vs 2010 Lexus ES 350 |work=Motor Trend |date=March 2010 |access-date=2011-06-03 |archive-date=2018-08-10 |archive-url= https://web.archive.org/web/20180810010854/https://www.motortrend.com/cars/buick/lacrosse/2010/2010-buick-lacrosse-2010-lexus-es-350-comparison/ |url-status=dead }}</ref> In 2010, Buick became the fastest-growing automotive brand in America and attracted a younger customer demographic.<ref>{{cite web|url= http://adage.com/article/news/advertising-buick-fastest-growing-car-brand-america/145397/ |title=Fastest Growing Car Brand in America?

An all-new Regal sedan, a smaller model based on the European [[Opel Insignia]], was re-introduced for the 2011 model year after a seven-year absence. For 2012, the all-new [[Buick Verano|Verano]], which was a compact sedan based on the [[Chevrolet Cruze]], joined the lineup. Additionally, the performance-oriented Regal GS officially went on sale and became the first Buick in almost 20 years to be offered with a manual transmission and a turbocharger. Buick also entered the hybrid market with the introduction of [[eAssist]] technology on the 2012 LaCrosse and Regal which helped improve fuel economy ratings by as much as 38% over the regular gas-engine versions. Meanwhile, sales of the Enclave crossover remained strong. In January 2012, the all-new [[Buick Encore|Encore]] mini crossover was unveiled at the North American International Auto Show in Detroit. Also in 2012, a turbocharged version of the Verano was introduced and the Enclave was redesigned for the 2013 model year. In 2013, GM confirmed plans for a "hybrid global brand" which includes [[Opel]]/Vauxhall and Buick using more synergies between the brands.<ref>{{cite web|url= http://gmauthority.com/blog/2013/06/opel-buick-to-expand-product-sharing/|title=Opel, Buick To Expand Product Sharing, Become A "Hybrid Global Brand" |date=17 June 2013}}</ref><ref>{{cite web|url= http://media.gm.com/content/media/intl/en/opel/news.detail.html/content/Pages/news/intl/en/2013/opel/06-26-Tina-Mueller-New-Chief-Marketing-Officer.html|title=Tina Müller New Chief Marketing Officer and Opel Board Member |access-date=2013-09-28|archive-url= https://web.archive.org/web/20130925013435/http://media.gm.com/content/media/intl/en/opel/news.detail.html/content/Pages/news/intl/en/2013/opel/06-26-Tina-Mueller-New-Chief-Marketing-Officer.html|archive-date=2013-09-25|url-status=dead}}</ref> LaCrosse and Regal were refreshed for the 2014 model year.

The Verano compact sedan was dropped from the Buick lineup in North America in 2017. With GM selling off the Opel/Vauxhall division to [[PSA Group]] in March 2017, Buick is expected to move away from sharing the Opel model/designs upon the completion of the current generation vehicles.<ref>{{cite news|last1=Frost|first1=Lawrence|last2=Taylor|first2=Edward|title=PSA targets Opel turnaround as GM exits Europe |url= https://www.reuters.com/article/us-opel-m-a-psa-idUSKBN16D0J1 |access-date=10 March 2017 |work=Reuters |date=Mar 6, 2017}}</ref>

For 2018, Buick replaced the Regal sedan with an all-new model offering hatchback and station wagon body styles. This new Regal was the first hatchback from Buick for the North American market since the 1987 Skyhawk and the first station wagon since the 1996 Roadmaster. A sub-brand was also added in 2018 to accompany Buick, with the Avenir badge being applied to its top-of-the-line level trims, utilizing the same strategy as GMC's successful Denali sub-brand.<ref>[http://gmauthority.com/blog/2016/09/buick-announces-avenir-sub-brand-to-join-future-products-in-2018/ "Buick Announces Avenir Sub-Brand To Join Future Products In 2018"] from GM Authority (September 1, 2016)</ref> 2019 would be the last year for the Cascada convertible globally and the LaCrosse sedan for the North American market.

====2020s====
[[file:Buick Logo.png|thumb|Buick logo used until 2023]]
New for 2020 was the [[Buick Encore GX|Encore GX]] crossover which slotted in between the existing Encore and Envision. The Regal hatchback and station wagon were discontinued for the North American market in 2020.

In June 2022, Buick Global Chief [[Duncan Aldred]] announced that Buick would transition its entire line-up to electric vehicles by 2030.
