well for karting around the honeys and picking them up as well there are a couple answers IMHO.
1) M3- maybe a little cramped,but hey, you can get to your spot faster
2) Old 5 series - lots of girls if you pack it and, more room for system. Also insurance is not that bad
3) Dodge Intrepid (what i drive) - plenty of space in cabin and in trunk
, airs out well over night
, and also, ability to sit on 19's without modification
just my $.02 again
