I've had the car for about 9 months now. The driving experience has been great fun. The only problem I've had has been the recent snowfall (I do know that the car is not meant for driving in snow). The other problem was that I acquired the car through BMW's European Delivery. The so-called "re-delivery" was hopelessly late. And BMW will not compensate you when your car arrives late. Neither will the dealership. Beware of the European delivery!
Brakes, acceleration, gearbox.
Windows tend to get foggy very easily. This has not happened with some other BMWs I owned.
