1: 1969 Pontiac Grand Prix SJ
There is no denying the Pontiac brand was a prominent part of early automotive industry. When you thought about a performance car, the Pontiac Grand Prix was one of the most iconic. The Grand Prix SJ was based on the same platform as the Monte Carlo. Aside from the awful-looking front clip, the Grand Prix SJ was a solid car. You can find these from time to time for a reasonable price.
Upgrading one of these can be done for close to nothing and the car can perform with the best. There are other muscle cars from this era that look a lot better. But the Grand Prix SJ is a well-appointed muscle car designed to offer an alternative to the Monte Carlo. Pontiac is now defunct and this car is a historic piece of the automotive industry.
