I'm not too keen on the re style on the Mustang either. Mainly the back end treatment. I think it looked better prior to the "face lift".
The Camaro is a really nice looking car in my opinion, BUT, if they were trying to get the "retro" feel or look then I think they came up short. It does remind me of a first gen but it sure could have been alot closer without making it a clone.
The Dodge.....well, it's a Dodge. LOL!! Ok just messing with you MOPAR guys.
It looks really good I think. From a retro standpoint the look takes me straight to the original in my mind. And with the bigger hemi is a great factory effort. Add a blower, better brakes, better suspension and a few other things and you have one hell of a sweet car! But I am still a Chevy guy and I think if you did the same mods to a new Camaro you'd have a better car than the Mustang or the Challenger.
Theres my 2 cents.

And thank you Todd, I had been looking for some kind of comparo on these cars.
