Sorry to have purchased this car
 Car is very nice except for a problematic idling issue. Been to the dealer over 6 times (lost count thereafter), talked with BMW of North America several times. No satisfaction even though the car is under warranty.  If you are looking to own a BMW hope that you get a good one and not a lemon as I have.  I have owned several BMWs over a 15 year period and feel completely let down by the situation.  Two more observations: sound system is average, very average. Wind noise from the sunroof is annoying.
