The Buick Special was usually Buick’s cheapest model. It started as a full-size car in 1936, returned in 1961 as a compact, became mid-size in 1964, and introduced the V6 engine that General Motors used for the next four decades.

History of the Buick Special
The Special’s ancestry runs through the Series 40 of 1930, which used a 257.5-cubic-inch overhead-valve straight-six of 80.5 bhp and was Buick’s most popular model that year with 74,257 built. After a pause in 1931, the Series 40 returned for 1934–35 with a 233-cubic-inch straight-eight of 93 bhp. It was the most affordable Buick, offered in six body styles: the five-passenger Sedan Model 41 cost US$925, and every Buick had a dashboard selector that allowed low-grade or premium fuel.

For 1936 the whole range was given names and the Series 40 became the Special, Buick’s entry-level full-size car. The first Specials rode on a 118-inch wheelbase, raised to 122 inches for 1937 when all Buicks grew and the engine became a 248-cubic-inch eight. There was a full restyle in 1939, and for 1940, the only year it was offered, a four-door convertible Sport Phaeton of which just 552 were built. Prices ran from US$795 for the Business Coupe to US$925 for the Touring Sedan or Convertible.
The 1941 cars were all new, and the Estate Wagon moved from the Super into the Special range. A shorter 40-A series shared its body with the 1941 Oldsmobile Series 70. Production stopped on 4 February 1942. When it resumed, only the larger B-body Special was offered, in four-door sedan and two-door sedanet form — a rare model, under two per cent of Buick’s 1946 output.
A new body arrived halfway through the 1949 model year, with nine grille bars that also served as bumper guards, and a better-equipped Special DeLuxe. The 248-cubic-inch engine was replaced in 1951 by the larger Fireball straight-eight.
In 1961 the name returned on a completely different car: one of GM’s three new compacts, sharing its chassis, engines and basic sheet metal with the Pontiac Tempest and Oldsmobile F-85. The Special introduced the modern Buick V6, which became a core GM engine and lived on in upgraded form until 2006. By 1970 Special was no longer a standalone model, though the name was used again as the entry trim of the Century from 1975 to 1979 and from 1991 to 1996.
