25: 1987 Buick GNX
Where do we start with the Buick GNX? The car is the stuff of legend in the automotive world. More so in recent years, as a new generation of drivers starts collecting these vehicles. The GNX, which was the Grand National, was a turbo-powered sports car built on the GM G-Body platform (via Road & Track).
These cars were the leaders of the pack when it came to sales numbers and GM kept the platform going for over a decade. In recent years, the next generation of automotive enthusiasts has fallen in love with turbocharged V6 sports cars.
