 It seemed promising at first, but after a few months I'm done with it. There are more rattles than an old Volvo, the 3.0 is weak, iDrive is useless, the run flats are crazy expensive and have NO traction in snow, and it rides worse than my F-150 4X4. Actually, my F-150 is built better, more dependable, has equal handling and performance, and gets about the same gas mileage. Now the evaporator is leaking freon. Maybe this 3rd trip in the dealer can resolve these issues.
