Why it looks wrong? Here's my 2 cents.
The wheels on this thing looks like it uses offset from a corolla / civic. The dead giveaway is the navy one with BBS FR with rear flares as big as this one, and uses high offset wheels and looks like same width front and rear, you tell me whats wrong.
Next is the proportions. looks bloated except for the front. The sides, and the way the rear fenders and rock panels are very 350z like (again, bloated). Looks like a fat chick with a mean Halloween mask.
If they trim up the sides and the rear with more edge lines like the front, it may look more like a 2800 lb car. But then will look too close to the LF-A. The length of the car don't look proportional to me. Need to shorten the wheelbase a 2-3 inches from the rear, and cut the rear overhangs. Its a coupe with a hatchback pen line like the Celica was.
