1970 Buick GSX – $380,000
Much like the muscle cars that came before it, the Buick GSX was another GM creation. The car had all the performance of its stable mates, but it took things up a notch. This was not a Buick geared toward retirees and people who wanted comfort. The 1970 Buick GSX was a performance-built car, and it left a heavy reputation (via Motor Trend).
The value of the 1970 Buick GSX has continued to rise because the car is so rare. You’ll seldom see one of these on the road anymore and that’s because the production numbers were lesser. The 1970 Buick GSX is by far one of the most iconic muscle cars in the Buick division. The styling and attitude of the car made it an instant classic.
