I rest my case. Pretty much the same car.

It really depends on which years you are referring to. In '71 they did look very similar. But in the 1970 below, not so much. The 71s, like in the previous set of pics I posted, had duel headlights like the Challenger. The 71 Cudas (below) had single headlights.

Plymouth Barracuda

Dodge Challenger

I was talking mostly about the car itself minus slight cosmetic differences between Dodge and Plymouth that always existed between the "twin" cars like Dart/Valient, Aspen/Volare, Charger/Road Runner etc. Sure the headlights and grill and taillights are different but the main body of the car is the same to a large extent. Going back to my original statement, it's why T said they are pretty much the same car. I rest my case.
