Hell yeah Oh em gee, I was thinking of going out on a cruise at night with a girl I was interested in. Haha but there's no way I would play rock or rap. As far as the minivan goes, I got a lot of complements on my car, so no worries there.
most girls do, as long as a heavy metal or hardcore rap song isn't on the radio... and if you do, then don't have it just be "hey you wanna stop here for a while" so then you get to 2nd base. cuz most girls probably wont go out with you after that. have it be an innocent drive, steal a couple kisses, and she'll decide what she wants to do.
and its better if its not some lame minivan your taking her in. its cooler if its an older car, or at least a cool looking car...
