See, this is what the American companies need! More futuristic/next level looks. I'm so damn tired of the "retro" theme. The Mustang, Challenger, Camaro were amazing cars. Nothing we make now will be what they were before, so we are simply making watered down versions of great cars. Why not take what makes those cars great, use their identifiable design cues and make something new, something that by itself can be great, not simply because of a name.
Now I also agree that the tail lights kill the back, but the lines are perfect. Stick the new '06 "stang tails on it and it'll be all good.
