Ford Mustang II
The Mustang is as classic as American apple pie, a vestige from the glorious muscle car era thankfully still around today. The Mustang II, on the other hand, was a terrible idea. Instead of using the Mustang as a basis, they based it on the Ford Pinto, which was one of the worst cars. Remember the AMC Gremlin? Back in the day, it was said that the Gremlin could match or even outperform the Mustang II. Embarrassing!
