10: 1975-1980 Chevrolet Corvette
The ’75 Corvette was a departure from the previous generations of the car. What made it different? Well, the styling for one thing was a lot more modern. But it was under the hood that things got questionable. All of a sudden, the engineers had to deal with all kinds of emissions laws and regulations that completely diminished the performance of the car (via Edmunds).
The Corvette would go through several renditions of the design but it just didn’t connect with consumers. This generation of the car was not only a massive departure for the company but also a letdown for Corvette enthusiasts. On the positive side, this is one of the most affordable Corvette models on the used auto market.
