You have a bit of a disadvantage being a girl, frankly. I think if people see stickers or other cosmetic mods on a girl's car, they'll make assumptions.

Personally I think it'd be fun to keep it clean, throw the mods under the hood, and stomp the crap out of people. Then you can point at the macho ones and say "Youuuu got beat by a giiiirl! BWAHAHAHAHAHAA" :af:
