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.
