Comparing the Mustang gt to the challenger concept is not realistic because the concept has a 425 horse hemi engine. They are not in the same class or the same price range.

Compare the Mustang gt500 to the challenger concept. This will give you a more accurate price range. I'm guessing 45-50k for both.

Now if DCX makes a challenger to compete with the mustang gt at 30k. It will have a 300 hp motor and less costly tranny in it also to bring cost down.
