Good luck with the beemer man... GTI hugh? That's what I'm hovering around at the moment. You can get a 2.0 liter hatch back (GTI, A3, etc.) and mod the heck out of it (exhaust, intake, chip, suspension, etc.) and then take it to the track for a reasonable cost. Even put a trailer hitch on em to take the bike to the track.
That beemer would be super expensive if you hit another car... Not that I ever hit anybody while I was on my bike...wink, wink!
