get clear corners so they match the headlights instead of black housed ones

paint the rotors or get new ones that won't rust

get new lug nuts

get rid of that turbocharged plate in the front and get a genuine grand prix plate filler

lower the car

get stock tails for the car

re-paint or re-do both front and rear bumper fasias so that they are stock color, i think its battleship grey.

i just noticed you have an ebay bumper, get a geniune gm front bumper with the pontiac arrow head indentation.
