Buick GNX
Buick and performance weren’t generally two words that went together, but the GNX changed all that. The intimidating black two-door car shared a platform with the Monte Carlo SS and the Cutlass, but it’s what was under the hood that was different. The turbocharged engine was one of the fastest production engines ever used in a car (via Jalopnik).
The fact that it was a Buick only added to the distinct styling and performance that the car offered. The GNX, also known as the Grand National, has ballooned in value over the past couple of years as more enthusiasts have begun to enjoy the car.
