Models Offered

Buick Special – Series 40 –
The new Special was Introduced as late a 1949 style. This was the first Special with postwar styling beginning in 1950. Most prominent was the cars “bucktooth” grille, consisting of a series of bumper guards. Special Series cars had three rectangular Ventiports on each hood side. A unique feature of the cars released in late 1949 was that the hood was opened through a Ventiport key and slot system; 1950 production cars had inside hood releases. Specials had no side body moldings.

Special Deluxe models had plusher interiors, a full-length body side molding, bright window outlines and “Special” in script on the front fenders. They were indicated by the code “D” in the model number.

Buick Super – Series 50 –
The Super shared all other Series’  all-bumper guard grille, and offered more rounded styling. “Super” in script appeared on front fenders, just above the full-length lower body side molding. A new, long wheelbase sedan featured a plusher interior than other Supers, which normally had cloth interiors of finer material than the Special. Supers had three Ventiports on each hood side. The Model 56C convertible had leather power seats plus power windows and top.
Buick Roadmaster – Series 70 –
Buick’s senior line always featured larger engines and plusher interior trims than comparable Super models, and were readily identified by the four Ventiports on the hood sides. “Roadmaster” in script was found above the full-length body side molding on Roadmasters. The cars with  “Sweepspear side moldings had “Roadmaster” in script engraved in the upper body trim strip behind the door trim (except on the Model 79 and 72R which received the Sweepspear mid-year).
