The 1950 Buick Roadmaster restyling featured a grille so toothy that Consumer Reports commented that “a toothbrush for the dentures comes extra.” The Sweepspear had proved so popular in its first year that it was made standard on most body styles at the beginning of the 1950 model year, and on the station wagon and a new 4-door Riviera (not a hardtop) mid-year.
New body styles for 1950 were a pair of upscale four-door sedans, one of which was tagged Riviera, which were stretched an extra four inches (102 mm) . The following year only the Riviera of these two sedans remained, and it would remain in the model lineup through 1953. Like the convertibles, all Rivieras, be they 2-door or 4-door, now came with both power windows and power seats as standard equipment. The only change under the hood was that hydraulic valve lifters were fitted to the engine.
