In the year I've owned my m3 I have determined that it is more of a dick magnet. Girls just think it's a BMW and seldom know what an M3 is. Like I said in the "You know you own an e9x m3 when..." thread:
"Guys can't wait to get in your car, and girls can't wait to get out."
I have fun driving my car no matter who is riding shotgun. Guy friends welcome second gear on-ramp pulls and casually sliding around city blocks. I have tried this with girls and it is instantly obvious that I am the only one having fun. They sit there petrified, gripping any handle they can find probably thinking what a crazy asshole I am. Oh well.
Anyone have similar experiences?
