I called Irvine bmw today and talked to the guy who's working on my ///M. He said only one thing was wrong. My half shaft broke (the half shaft is what spins the rear wheels). So basically when Vince was trying to drive back up to my friend's house, the car was moving on 3 spinning wheels and not 4. Vince said he noticed how the car kept moving sideways and stuff. Also the broken half shaft is wat caused the clutch to slip and what not.
