Buick Century Custom specs: 1975-1977

The Buick Century Custom replaced the Buick Century Luxus for model year 1975. The Custom was more luxurious than the base model, including nicer wheels, plus the coupes received the formal roof-line as opposed to the base models, which got fastback styling. For 1976, the Century lineup received a new nose, but the coupes spun off in their own direction looking nothing like the sedan or station wagon.
