1956 Buick Series 70 Roadmaster Convertible Coupe

  • Chassis Number: 7C3042813
1956 was the final year of the sixth-generation Roadmaster. Introduced in 1954, the chassis was lowered and widened relative to its predecessor, power was from a new 322 cubic-inch V-8 engine, and the bodywork was more streamlined. The styling of the Roadmaster was similar to the lesser models in Buick's lineup, although with four fender-mounted 'ventiports' - one more than the 'lesser' models.

During the production lifespan of the sixth generation Roadmaster, Buick update the look, with the 1956 model distinguished by twin chrome strips on the trunk lid, 'bomb sights' atop both front fenders, added 'Roadmaster' script in several locations, and a chrome side strip with less of a dip toward the rocker panel. The interiors featured full carpeting, chrome bands on the seats of two-door models, rear armrests on sedans, and posher nylon, broadcloth, and leather upholstery combinations. The list of standard equipment on the 1956 Roadmaster included power brakes, power steering, Perimeter Heater, an improved variable-pitch Dynaflow automatic transmission, backup lights, windshield washers, glare-proof rearview mirror, electric clock, deluxe wheel covers, foam-cushioned seats, foam-backed carpets, padded dash, and, on certain models, power windows and a power seat.

This particular Roadmaster Convertible is one of 4,354 examples produced for the 1956 model year. It is finished in a two-tone color combination of Tahiti Coral and Dover White over a black and white leather interior. It has power brakes, power windows, power steering, power seat, and a power-operated soft top. There are wide-whitewall tires wrapped around wire wheels, and there is a Selectronic AM radio and under-dash heating controls.
