Final production version jeeps built by Willys-Overland were the '''Model MB''', while those built by Ford were the '''Model GPW''' (''G'' = government vehicle, ''P'' = 80" [[wheelbase]], ''W'' = Willys engine design). There were subtle differences between the two.<ref>{{cite book |last=Allen | first=Jim |title=Jeep: Collector's Library |publisher=MBI |year=2003 |pages=36–39 |isbn=978-0-7603-1486-9}}</ref> The versions produced by Ford had every component (including bolt heads) marked with an "F", and early on Ford also stamped their name in large letters in their trademark script, embossed in the rear panel of their jeeps. Willys followed the Ford pattern by stamping 'Willys' into several body parts, but the U.S. government objected to this practice, and both parties stopped this in 1942.<ref>{{cite book |last=Scott |first=Graham |title=Essential Military Jeep: Willys, Ford & Bantam models 1941–45 |publisher=MBI |year=1996 | page=25 |isbn=978-1-870979-76-4}}</ref> In spite of persistent advertising by both car and component manufacturers of contributions to the production of successful jeeps during the war, no "Jeep"-branded vehicles were built until the 1945 Willys CJ-2A.

The cost per vehicle trended upwards as the war continued from the price under the first contract from Willys at US$648.74 (Ford's was $782.59 per unit; these figures are equivalent to ${{inflation|US-GDP|648.74|1941}} and ${{inflation|US-GDP|782.59|1941}} in {{inflation/year|US-GDP}}, respectively{{inflation/fn|US-GDP}}).<ref name=Zaloga>{{cite book |last=Zaloga |first=Steven J. |title=Jeeps 1941–45 |url= https://archive.org/details/jeeps194145zalo |url-access=limited |publisher=Osprey Publishing |year=2005 | page= [https://archive.org/details/jeeps194145zalo/page/n11 10] |isbn=978-1-84176-888-5}}</ref> Willys-Overland and Ford, under the direction of [[Charles E. Sorensen]] (vice-president of Ford during World War II), produced about 640,000 Jeeps towards the war effort, which accounted for approximately 18% of all the wheeled military vehicles built in the U.S. during the war.<ref>{{cite web|url=http://gearheads.org/history-of-jeep/|title=The History of Jeep|date=17 May 2012|work=Gear Heads |access-date=3 July 2012 |archive-date=February 24, 2013|archive-url= https://web.archive.org/web/20130224081801/http://gearheads.org/history-of-jeep/}}</ref><ref>Borth, Christy (1945).

Jeeps were used by every service of the U.S. military. An average of 145 were supplied to every Army infantry regiment. Jeeps were used for many purposes, including cable laying, [[sawmill]]ing, as firefighting pumpers, field ambulances, tractors, and, with suitable wheels, would run on railway tracks. An [[amphibious vehicle|amphibious]] jeep, the model GPA, or "seep" (Sea Jeep) was built for Ford in modest numbers, but it could not be considered a success as it was neither a good off-road vehicle nor a good boat. As part of the war effort, nearly 30% of all Jeep production was supplied to [[United Kingdom|Great Britain]] and to the [[Soviet Union|Soviet]] [[Red Army]].
