34: 1979 to 1985 Buick Riviera
The Rivera was another car in the GM portfolio that went on a diet at the turn of the new decade. As rising fuel prices and EPA regulations set in, GM had to design more fuel-efficient vehicles. Of course, this was still during a time when V8 engines were in play so the Buick still had a powerful V8. The classic design is iconic among GM vehicles and there are several different things you can do to this car. First and foremost is compatibility with most of the GM G-Body platform. There was also the T-Type, which was a turbo-powered option that was similar to the Regal.

The Riviera is one of the most affordable classics you can get. But with classic car values rising, the Riviera is also going to rise in value. The solid design coupled with the ability to host a V8 engine gives the car a lot of potentials. Classic car enthusiasts would be hard-pressed to find a better platform then the Riviera due to its durability.
