First, a miata is not gonna "pull pussy" on the fact that they're fairy cars. I mean, unless the girl is kinda manly and wants a manbitch, then forget using a miata to pick up a gir.

Second, try telling a girl you have a BMW, then saying, "it's a 1992/3/4/5/6/7/8 model"
Early to mid '90s BMW isn't going to impress them unless they live in a trailer and DD a metro OR they're into cars and know the E36 is a good autoX car... in that case the little fairy car might work.

But lets be honest, if it's a "car girl", she's PROBABLY going to want a guy driving a manly or decently fast car; if it's just your average girl, then it can generally just be nice and clean.
