7: 1987 Buick GNX
Although it was released much later than the original muscle car era, the Buick GNX is very much worth considering. The car is one of the only turbocharged V6 GM cars based on this platform, and the performance today is still as exceptional as before. The unique things about the GNX were its blacked-out appearance and the stripped-down style of the car. You’d never know that this was a Buick Regal, as the styling was all its own.
The 1987 Buick GNX was only available in a single color combination, and the car looks menacing even to this day. Values on these cars have been going up as consumer taste for 80s muscle cars continues to go up. There is no doubt that the 1987 Buick GNX is one of the rarest cars on the road.
