Great renderings and exactly what I expected a modern Challenger to look like. Same goes for the Camaro concept. I'm a little worried that it is a little too much like following a box recipe for "How to make a new 69 Camaro or 70 Challenger in 12 easy steps." Ford has definitely had some success with the modern 67 Stang though.
I probably don't hold the popular opinion when I say that the current modern retro-craze is still just another fad that will PROBABLY end within the next few years. It's too bad that these great looking cars won't be in showrooms until late '07 at the earliest. And knowing how long it takes for the Big 3 to update styling over the course of a product life...they may be coming into the game too late.
Just my $.02
