Being a Windows car...
you may not need specialized training, but you can expect it to stall unexpectedly which often forces you to replace the engine. Opening and closing the rear window might allow you to restart start it, but only after the third time you try. The fact that you are asked four times if you *really* want to turn off the radio is considered a feature. Don't forget that every time they repair the M4, you need to buy a new car.
