Buick GSX
The Buick GSX was another muscle car that came out of Buick and the idea was to combine performance with luxury. Like any Buick from this period, the body of the car was rather large. But the performance more than made up for it with a supercharged engine and enough pep in its step (via Hemmings).
The Buick GSX was one of the most well-known cars to hit the roads during this period and a lot of great effort went into the design of it. Drivers remember the way that the car felt when it hit the road and what made it a great ride even back then.
