This 1967 Buick GS 400 Convertible is the quintessential gentleman’s muscle car — combining serious big-block performance with Buick’s signature luxury and refinement. With only 2,140 GS 400 convertibles produced in 1967, this is a rare and highly collectible classic muscle car.
The Buick Gran Sport debuted in 1965 as a performance option for the Skylark before becoming its own standalone model in 1966. By 1967, the GS 400 was the top-tier performance model, while the newly introduced GS 340 served as the entry-level version.
Although equipped with a 401 cubic inch V8 engine, the GS 400 was marketed as a “400” due to General Motors’ 400 CID limit on mid-size cars at the time. The result? One of the most underrated and refined muscle cars of the 1960s.
Under the hood sits the legendary 401 cubic inch V8 engine, topped with a single 4-barrel carburetor and the iconic twin-inlet “Star Wars” air cleaner. Rated at 340 horsepower, the GS 400 delivered serious performance while maintaining Buick’s smooth, luxurious driving experience.
