Series 70. 152 bhp, 320.2 cu. in. OHV inline eight-cylinder engine, two-speed Dynaflow automatic transmission, front and rear coil-spring suspension, and four-wheel hydraulic drum brakes. Wheelbase: 126.25 in.

The beginning of Buick’s new post-war designs came in 1949, as did some new models. Innovations included the introduction of the two-speed Dynaflow transmission and solidly built, heavily trimmed automobiles that created a new, modern look, different from the flowing Art Deco designs of the 1930s and 1940s. At the top of the line was the posh Series 70 Roadmaster. On the 1950 models, the Roadmaster, along with other Buicks, was distinguished by a large, bright, “toothy” grille that descended below the car, giving it a highly distinctive and unique front-end appearance.

The Roadmaster Convertible offered here, one of approximately 3,000 built, was professionally restored to exacting standards from a good, solid, original car. It has scarcely been driven since its completion and has enjoyed climate-controlled display in the Howard and Norma Weaver Collection. The restoration remains in very good older condition, with excellent fit and finish of the straight, original body panels, which are finished in period-correct dark metallic blue. Most of the chrome and stainless-steel trim items have been professionally refinished and remain in fine overall condition, as does the interior, upholstered in brown leather with matching door panels and carpets, and the tan fabric Haartz convertible top. Importantly, the power top mechanism has been restored to function correctly.

Underneath the car shows quality restoration work and hardly any signs of use; the engine is extremely clean and highly detailed and has all of the correct hose clamps, decals, and labels.

This is one of the finest automobiles in the Weaver Collection as well as one of the nicest 1950 Roadmaster Convertibles in existence.
