I have seen the 2010 Mustang. It was in Long Beach, CA a couple months ago. I got into a group of about 30 people (not one other Mustang enthusist, though) to do a focus group on the full exterior, and a mock up model of the interior.
It was a full, rolling clay. No one noticed it was clay - clays are that good.
Great look, that will have some saying that the front end looks a little like the new Camaro (the grill area, anyway). My complaint with the car is a drastic departure from the last 45 years: the rear bumper is not straight flat from end to end. It goes diagonal towards the rear tires at about 1.5 feet in, like: /----\ (at least on the clay). Fans raised a fuss when they turned the taillamps vertical in 1994. This is just as bad.
But overall the car is the most agressive look the Mustang has seen in its history. I'd have to give it a thumbs-up.
