But Jo can get you the best deals around, he gave me a ~$150 discount on a UUC exhaust, while when I called UUC they wouldn't give me a dime of discount unless I bought two things at once. Now when you say 12K I hope that's including instal, lol
EDIT: By the way, am gonna be in Florida from the 24th-27th of this month, one of those days I'll be down in Miami (yes going to go see Jo) I'd love to see your bimmer
