14. Buick GNX
By the 1980s, the golden age of muscle cars was gone, but Buick managed to squeeze another model on the market. It is the GNX that was equipped with a 3.8-liter turbocharged engine which replaced a naturally aspirated V8. The GNX or the Grand National was one of the fastest cars at its time, but it was out by 1987. At least it received a proper sendoff with the limited edition GNX.
