be unique and do something that no one is doing these days...make a sleeper. shit-can the body kit, spend the money on some quality time on a dyno, get the engine tuned and boosted to hell....paint it flat black with stock bodykit...then blow some doors off of the wannabee racers that think flash wins them the race.
-i am not advocating street racing- only sanctioned racing with proper safety equip and controlled environment.
In the end...build a car that is fast....don't just build a car fast.
