Me too. I've never been particular on car manufacturers, there's always something from the big three that catches my eye. I stumbled across a '71 Scamp and I bought it. I had never even heard of a Scamp. But it was all over after that.
What non-Mopar car? I have always loved the '66-67 Chevy Nova II. Small, tight platform. Clean, boxy lines. You can build them to be unassuming sleepers or badass street machines born from hell.
