1955 BUICK ROADMASTER 70 RIVIERA COUPE

1955 was a memorable year in American car history. In that year, which saw the production of 7.9 million cars, Buick secured third place in the market with record sales of 738,814 numbers. Buick built their one-millionth V8 on March 16, 1955 and after twenty days completing the assembly of their eight-millionth car. That year 9.84% of cars manufactured in the United States, were Buicks.

The company was set up by the Scottish industrialist David Dunbar Buick in 1903, and began selling cars in 1904. Between 1907 and 1910, it came second in the market to Ford. For three years in the 1910s, two years in the 1920s and 1930s and during 1955-1956 period, it surpassed Chrysler’s Plymouth, one of the “Big Three”, to secure the third place.

Assembled in eight factories in the United States, the 1955 Roadmaster was introduced with three different models, 4-Door Sedan, a Convertible Coupe and the Riviera Hardtop Coupe. This model, the example in our Museum, uses the same body as the Oldsmobile’s 98 and Cadillac’s “C” with the Super series and shares their technical structure and specifications. Its comb-shaped front grill, the model was replaced that year with a honeycomb grill. 28,071 cars were produced.

Our 6-seater hardtop Riviera’s price was 3,453 Dollars. Power steering, luxury wheel covers, double-depth foam seat cushions and luxury carpet are standard equipment. Two-or three-tone paint, white wide wall tires, exterior rear-view mirror and air conditioning are optional.
