19: Plymouth Cricket
The Cricket itself wasn’t originally a muscle car. In fact, it was the furthest thing from a muscle car. But in recent years, it has become popular to do a Hemi swap on this dimunutive ride. The styling makes it a unique Mopar that most people have never even heard of or seen in years (via Hagerty).
The Cricket is by far one of the worst-selling Plymouth models of all time, which means you can find them for a cheap price. But the ability to swap out to a V8 motor makes the car a unique Mopar choice that you won’t find very often and you can make it fast and unique on your own.
