Century Sedan
We’re using the term ‘Sedan’, capitalized, as a proper-noun here. This extended name is used here to describe 1976-1977 Century 4-doors and station wagons. This is due to their quite varied appearance when compared to Century coupes during these two years.
All three body styles shared the same appearance up until 1975. However, the ’76-’77 sedans and wagons received vertical stacked quad headlamps and a unique grille. They also retained the ’73-’75 style tail-lamps even though the rear lights got updated on the coupe. The swooping rounded body lines of those earlier years stuck around here too, even though the coupe was doled-out a squared appearance these years.

Two trims were sold. These were base and Custom. The standard engine in the sedan was the 231 CID 2bbl V6 which made 110hp. Optionally you could get a 350 CID 2bbl Buick V8 which made 145hp. A 350 CID 4bbl Buick V8 was optional in the sedan but standard in the station wagon. This engine made 165hp. The 455 CID 4bbl Buick V8 was optional in the wagon. In 1977 that engine was replaced with a 403 CID 4bbl Oldsmobile V8 which made 185hp. Also added this year as a credit option was a 305 CID 2bbl Chevrolet V8. The very next year, the sedans, wagons, and coupes were all ‘on the same page’ again as far as appearance when they were downsized.
