 Exhilerating and fun when everything works! Love to drive my 2008 535i with Sport package- when it is not in the shop. Lots of power and totally responsive. Many problems which has been worked on under the factory warranty.1) entire head lamp module (less than 1 wk after delivery), 2)fuel pump, 3)fuel injectors, 4)car suddenly went into limp (lower power) mode when entering hwy- no solution yet from BMW(fortunately I was not in heavy traffic), 5)new gear shift handle, 6) iDrive goes crazy-deadblack screen. Hopefully, nothing else shows up. I love the way the car handles but the trips to the service department has become too aggravating! Selling before warranty ends!Bitter/sweet experience.
