Rental Company: Avis

Let's be real, your girl isn't just going to believe you have a Z4 all of a sudden. If she asks you why you rented something like this, just tell her you wanted to treat her like the royalty that she is, at least for a night. Just a warning: As much as she's going to probably want to jump your bones, after that line, we don't really recommend trying to get it in in this tiny car.
