21: Ford Mustang Cobra II
The Ford Mustang is perhaps one of the most iconic automotive brands in the world. However, like most automotive brands in the 1970s, the Mustang was also hit hard by the rising fuel cost. The Mustang II is the only Mustang ever based on a compact car platform. It shared its platform with the Pinto and this caused a lot of controversy among traditional Mustang enthusiasts (via Motor Trend).
The Mustang II wasn’t a bad car, but it fell short in many key areas. That meant buyers who wanted a Mustang had to look elsewhere. The sales of the Mustang II were poor, so you don’t generally see a lot of them on the road anymore. But in recent years, the fact that the car is a Mustang has made the price start to creep up. Nowadays enthusiasts are looking to take the Mustang II and swap a modern Ford Coyote motor into it.
