Editing Buick (section)

===Mexico===
Buicks were sold in Mexico from 1921 until 1962, when a [[protectionist]] policy on behalf of the government restricted the percentage of imported parts that could be used in the manufacture of vehicles and the sale of imported cars. From then onwards, all GM products were sold by Chevrolet dealerships. In 1990, after a heavy modification to the protectionist policy of the sixties, GM started assembling the Buick Century in Mexico, at the plant in [[Ramos Arizpe]], in the state of [[Coahuila]], just south of [[Texas]], and selling it through Mexican Chevrolet dealerships, so it was not uncommon for many people to call it "Chevrolet Century". In 1997, GM stopped selling Buicks in Mexico and the brand was not sold there until 2009.

With the announcement in 2009 of the elimination of the [[Pontiac (automobile)|Pontiac]] brand, it was speculated that Buicks would be sold once again in Mexico since there was a large network of Pontiac-GMC dealerships already in place. On July 24, 2009, Grace Lieblein, the new president of GM in Mexico, revealed that the Buick brand would be available in Mexico in late September of that year, after an absence of a dozen years, with the LaCrosse and the Enclave models. Buick shared the dealership floor with Pontiac and GMC until the Pontiac brand faded away in the summer of 2010.

On March 26, 2019, Buick announced that the Mexican division will offer only crossovers (Encore, Envision, and Enclave). The La Crosse sedan, Regal hatchback, and Regal TourX station wagon were dropped from the market as those brands were expected to be discontinued due to Opel's future (under new owner Stellantis). The Insignia is tied to the North American-badged Regal and Buick's decision to make the La Crosse exclusive to China.<ref>[http://gmauthority.com/blog/2019/03/buick-on-its-way-to-axing-sedans-altogether-trims-mexico-lineup-to-include-crossovers-only/ "Buick Trims Mexico Lineup To Include Crossovers Only"] from GM Authority (March 26, 2019)</ref>
