Nice BMW clearly lol. The civic guy would just give me the impression that he's a bit too into his car (and perhaps himself) and Im never going to care about it as much as he will and i happen to be into cars. Also, the BMW is a million times nicer inside and out from teh civic and lets face it, its not like we will be racing so who cares what he did to the civic.
But otherwise, I could care less what the man drives. No girl that dates you for your car is going to stay with you or stay true to you. I look for the man that suits me and if he drives a yugo, sure ill be a bit embarrassed but the car can be changed, teh man cant.
