1950 Buick Roadmaster Sedan

The Roadmaster, introduced in 1936, became Buick's premier model, with a larger engine and a finer interior. "Venti-Ports" -- the rectangular holes on the hood -- debuted for 1949. Though they served no practical purpose, they suggested exhaust ports on a fighter plane and quickly became a Buick trademark. Initially, Roadmasters boasted four Venti-Ports per side while lesser Buicks had just three.
