Buick produced the Series 80 model from 1931, this car sharing the 5,650cc straight eight engine with the Series 90, but built on a shorter chassis to market lower. The Series 80 was heavily revised in 1933, but then dropped in 1934. A new Series 80 was added to the model line up for 1936, but now carrying the name 'Roadmaster'. A 5,247cc straight eight powered 3 different Buick models. This Roadmaster was revised along with all Buicks until 1940 when an all new Series 70 Roadmaster was launched, and this ran until 1949 with an interruption for WW2. The 1949 Roadmaster gained the new GM C-body, and also the stylish new hardtop variant marketed as the 'Riviera'. The first V8 Roadmaster was produced in 1953, and a new body appeared in 1954 which was updated each year. In 1957 The GM C-body cars were given a new body on a 127.5-inch wheelbase shared with the Buick Roadmaster, Oldsmobile 98 and the Cadillac Series 62.

Buick Roadmaster Dynaflow 1949 Convertible - VentiPorts. Designer Ned Nickles fitted four lights on each side of his Buick, wired to flash with each cylinder to simulate the firing of the engine. On seeing these Harlow Curtice sanctioned fitting them onto production cars, and although they might have provided ventilation within weeks they became non-functional. Larger engined Buicks were given 4 VentiPorts whereas less models only got 3.
