The Roadmaster was built by Buick from 1936 to 1958, and again from 1991 to 1996. Roadmasters produced up to 1958 were built on Buick's longest non-limousine wheelbase and shared their basic structure with entry-level Cadillac and, after 1940, senior Oldsmobile models. Between 1946 and 1957 the Roadmaster also served as Buick's flagship. For 1957 new, lower-profile pillarless four-door sedan, two-door coupe and two-door convertible bodies graced the Roadmaster model which featured a more panoramic windshield with reverse slanted pillars. Other distinctive styling cues included a red-filled “Sweepspear” down the bodysides and a chromed rear lower panel in the area between the wheel arch and the bumper end. The infamous "Dagmar bumpers" continued at the front, a new centered fuel filler was located in the rear bumper, at the ends of which the single or optional dual exhaust passed through. Interiors featured a padded dashboard and were cloth and vinyl in four-door, vinyl in two-door, and leather in convertibles. A new 364ci V8 engine was rated at 300 horsepower, while new ball-joint suspension improved handling. New too was the mid-year introduction of the Model 75 that featured standard power seats and windows, carpeted lower doors, a one-piece rear window (instead of a three-piece that was a design feature of the smaller Special and Century models), Deluxe hubcaps, and Series 75 script identification. Despite these significant upgrades, overall Roadmaster sales dropped to around 33,000 in 1957.
