2 cents of improvements:

-lose the nismo sticker and the front banner.
-lose the weaksauce front bumper and home depot grille
-lose an inch on the wheels. wheels are too big for the car, and driving on rubber bands looks like ass too

-gain a wing of some sort, though its nice wingless i think it needs something
-the stripe im actually feelin a little. its subtle and clean, matches the wheel colour nicely.

otherwise i'd rock that car.
