1975 Chevrolet Corvette
The ’70s had not been a good decade for the Chevy Corvette. Around this time, it did not see a lot of changes when it came to the interior and body. Sadly, it was outfitted with a slower and smaller engine. It only had 15 more hp than what it was using 20 years before that. While it was a truly gorgeous car, it was not enough to make up for the decline in power. It did not hold up, which is why it is on the list.

1982 Chevrolet Camaro
The car in the photo is an example that even though you have put a lot of thought into the design of a car, it will not always be great. The 1982 Chevy Camaro had a couple of issues. One of these would be the engine. While it was equipped with a 5.0-L engine, it still failed to go past 200 hp. The car would take 20 seconds to go from 0 to 60. This was already considered slow even for the time.
