2: Buick Century GS
Buick is another brand that’s well known in the muscle car business and the Century was one of the well-known models. The Century GS had a lot of interesting features to it but the look was different than the average muscle car. The standard 455 Stage 1 big block was a massive engine that offered quite a bit of performance at the time.
When you think of the muscle car era, the Buick Century GS is not a well-known entity. But the performance is above standard and there were quite a few of these cars manufactured. A lot of drivers consider the Century GS as the last “true” Buick muscle car, although the GNX would come later on down the road.
