Buick Century Coupe specs: 1976-1977

This page was created to point out the Century that diverted off the normal path, the 1976-1977 Buick Century coupe. Because these weren’t the ‘conformity coupes’ of ’73-’75.

The previous coupes shared a front end with the sedans/station wagons. The taillights were shared with the sedans, but the coupe went off on its own for 1976. The entire front clip here is more squared off with the headlights being in a horizontal arrangement rather than vertically stacked like on the ’76-’77 sedans/wagons. The squared body line of the nose is followed through to the updated doors as well. The taillights here have a more slender shape on the coupes, while the sedans kept the older ’73-’75 appearance.

However, these kept the ‘fastback with large quarter window’ roof-lines of the previous year, while the Century Custom and Regal coupes carried forward the formal style roof-lines. To further differentiate the ’76-’77 Century coupe, Buick took a page out of the Olds Cutlass ‘S’ marketing book and slanted the nose back, whereas the Regal has an upright appearance.
