its just based on that fantasy that guys love a chick who knows about or is into cars. so when some guys see a chick with a hooked up car they think she's just hanging around to get a rise out of a few of the guys drooling and mentally whacking off to her, lol. through the many buckets I've driven/owned, I've been in several clubs and all the female members have always been cool and acted just like one of the guys per say, but once in a while you do get one who trys to play on the "I'm the only girl in the group, so pay extra attention to me", lets be real it happens. I dunno, maybe its just that tiny bit of male chauvanism in all guys that when you see a girl participating in a "guy activity", a lot of times you think shes just doing it to be seen or trying to get some free installs, LOL(which I have seen and also fallen victim to

) "wheres Crystal? after you installed those coilovers and then her exhaust she hasn't come back to one meet" LOL but that can go both ways, male or female though, its just harder to resist a pretty face.
me personally I don't believe that and I accept people on how they present themselves to me. in the end sex has no determination on how a person will carry themselves.
