20: 1962 Dodge Dart 412 Max Wedge
Just having a brand name like the “Wedge” doesn’t bode well for a performance car, and the Dart 412 suffered because of it. During the sixties, Dodge was entering into the drag racing scene and this was their foray. The notable Dart 412 boasted a whopping 420 HP, which was quite high at the time. Fortunately, the engine was cramped into a very tight engine bay and this made working on the Max Wedge increasingly difficult. If you could get over the restrictions of the engine bay, the Dart 412 was not a very upgrade-friendly muscle car.
Another common problem that is even worse than its reliability is the body rusting. These older generation Chrysler cars are notorious for rusting. Dart 412 was not immune to this and if you happen to obtain a Dart from a salty area, you’re in for a lot of work. The value of these cars isn’t worth all the effort that you’ll have to put into it.
