 I bought the car in 5/07.  The hardtop has been fixed once.  The seatbelt metal clip put a few dents and scratches on the inside of driver's door.  Driver seat is uncomfortable despite adjustment.  Run flat tires are heavy and don't perform so well.  No room for spare tire.  iDrive freezes up occasionally and service dept can't duplicate it, and therefore they can't fix it. "Engine malfunction, reduced power" came on at 21000 miles in 10 months, now pending repair.
