The 1950 restyling featured a "toothy" grille. The Sweepspear design was made standard on most body styles at the beginning of the 1950 model year, and on the station wagon and a new long-wheelbase sedan mid-year. The long-wheelbase sedan was lengthened by 4 inches (102 mm)). Like the convertibles, the Riviera and the long-wheelbase sedan came with power windows and power seats as standard equipment. Overall Roadmaster sales fell to 75,034, with Roadmaster's share of total Buick output plummeting to 12%.
