I think they could lower the wing a bit, keep it, but make it lower to the back.
Otherwise - Wow! 500hp in a stock car, that thing isn't going to be affordable. I love the looks of it, I love the muffler on the side and the black hood, and I like that they covered the back windshield (I don't like the back windshield on the standard models, takes away from the look of the '69, which didn't have back windshields).
Ford sells amazing crate motors, and like one said "you can build one w/ that power for 15k" well, stock power always costs more than aftermarket power. You know why? Because they have to add the cost of working on the engine/building costs/labor. Not to mention crate motors come with tons of furthur potential.
Rice or not, this car will kick *everythings* ass, stock vs stock. And don't go on about how for the cost of this car you can make an aftermarket '85 mustang gt perform just as well, that's comparing watermelons to apples. You can build a house yourself much cheaper than buying one pre-made, same with cars. The labor costs all the extra money, that and speciality of the car itself.
I'm thinking $90,000 easily...Time to ask mom to let me into their bank account ^_^
