Don't think NASCAR allows you to run a Yoda motor in a Chevy body, or vice versa, So........ My guess is it was a Chevy, the tail lights also looked like Impala lights and if ya look at the grill opening, definately NOT Toyota, also from the side, the rear windows are definately of Chevrolet origin... They may have taken an Impala and plastered Toyota decals on it so Joey would not get into trouble with JGR...
