14: Volkswagen Type 181
This is probably one of the ugliest sports cars that came out of the 1970s and it had a Volkswagen badge slapped on the front of it. This car was an attempt by VW to gain some of the consumers back that the company lost during the muscle car era. Unfortunately, this was the furthest thing from an actual sports car you could get (via Hagerty).

Take one look at the car and you’ll instantly be able to tell that Volkswagen didn’t have a real plan. It looks capable of going off-road, but it doesn’t do that well. Its performance is also not even close to being called exhilarating. Yet values of this thing continue to rise to obscene levels.
