The sixth-generation Buick Roadmaster launched as a 1954 model. These redesigned flagship cars featured a chassis that was lowered and widened relative to its predecessor, which contributed to greatly improved handling. Under the hood was a new 322-cubic-inch V-8 engine, replacing Buick’s long-running Fireball straight-eight. Redesigned bodywork was more streamlined, and while the exterior of the Roadmaster strongly resembled lesser Buick models, an extra fender-mounted “ventiport” (among other subtle cues) distinguished it: Roadmasters got four, while the other models made do with three.
For 1955, the Roadmaster gained lower rear fender bands, gold-colored decklid script and hood ornament, gold-accented grille, and bars on the wheel covers to further set it apart from other models in the lineup. In addition to all the features found on other Buick series, the 1955 Roadmaster also included power steering, backup lights, brake warning signal light, electric clock, windshield washer, custom wheel covers, and double-depth foam seat cushions as standard equipment. Engine output increased for 1955, and the Dynaflow automatic transmission was improved with variable-pitch technology for better acceleration.
The convertible example offered here is finished in Titian Red with a white and maroon leather interior. The car features power steering, power brakes, power windows, Selectronic radio, and a power-operated soft top. It rides on wide-whitewall tires mounted to steel wheels with full covers. With only 4,730 Roadmaster convertible produced for the 1955 model year—far fewer than the coupes and sedans—this well-presented example remains highly desirable.
