Buick (/ˈbjuː.ɪk/), formally the Buick Motor Division, is an upscale automobile brand of the American manufacturer General Motors (GM). For much of its existence in the North American market, Buick has been marketed as a premium automobile brand, selling luxury vehicles positioned above GM’s mainstream brands, e.g. Chevrolet, while below the flagship luxury Cadillac division.
Buick has the distinction of being the oldest active American marque of automobile, and the original Buick Motor Company was the cornerstone of the establishment of General Motors in 1908. Before the establishment of General Motors, GM founder William C. Durant served as Buick’s general manager and major investor.
