16: Chevrolet El Camino
The El Camino has been on a hot streak lately in the muscle car market with values soaring to obscene levels. But, that doesn’t mean that this car is worth the high price tag. At the end of the day, the El Camino was a failed project by GM, and the car had a lot of shortcomings that are tough to overcome (via Car Gurus).

The build quality on the 1980s models was questionable at best, and the reliability started to go out the window too. The performance of the El Camino also wasn’t the most impressive either. The design was also very limiting, there was no back seat, and the car wasn’t good at going off-road like a real truck either.
