It was. Plymouth was Chrysler's head-on competitor for Ford's Ford Division and GM's Chevrolet Division for years. Since GM has managed to lose all brand identity through years of "badge engineering" and morphing of all formerly semi-autonomous divisions into just combined operations, DC no longer felt the Plymouth marque was of any value, preferring to hold on instead to the more valuable Dodge marque as their "bread-and-butter" line. A mistake? No...Dodges have been gussied up/better equipped Plymouths and vice versa since at least the mid 1960s. With that, they've also allowed Dodge-type product to slip into the Chrysler marque, such as minivans and the PT, which in another time, would've probably been Dodge branded products.
