14: 1964 Plymouth Barracuda
Often hailed as one of the most appealing Plymouths on the road, the Barracuda had some drawbacks to it regardless. Although the Hemi was a monster powerhouse of an engine, it wasn’t the most pleasant to work on. That’s why most restoration enthusiasts have swapped out for more modern powerplants. Then you have the polarizing design of the car, which some considered to be ugly at the time. The Barracuda does have a solid fanbase, but it also has its detractors.
Mopar had many hits at the time and the Barracuda was one of them. Unfortunately, with the high price tag and the abundance of design flaws, the Barracuda is a pain to own. In a lot of aspects, you can find a less problematic muscle car that has a lot more potential. Still, the Barracuda remains an icon among Mopar muscle car enthusiasts.
