RE: quality build of the challenger
Newer Dodges and Fords have upped their build quality, even over 3-4 years ago. Also, you can tell they're starting to actually put effort into interior comforts and design. Some of the Fords and Dodges actually have better looking interiors than some imports.
I'm talking about overall look and appeal. Design, materials, qualitly, etc etc.
American cars have stepped it up in the past few years, and I expect the Challengers to be no different.
