35: 1996 Buick Riviera – $10,500
The Riviera was one of the last supercharged V6 two-door cars to be sold in the Buick lineup. The appetite for these large two-door cars was all but gone in the 1990s, and the Riviera didn’t sell well. But nowadays, the car has found an entirely new audience and values have been creeping up (via Trinity Auto).
Drivers are not going to get their hands on one of these for cheap anymore. In the 2000s, these cars were essentially worthless. That has changed drastically and now people will pay a pretty penny if they want a Riviera from this generation. Topping it off, GM cars from this era were plagued with all kinds of reliability issues.
