We will soon have BMW sorted - i.e the importers:
-M badge outside in Europe - not US.
-Finland and Switzerland (?): mandatory roofrails
-US and Sweden: mandatory run flats - no so in Germany.
-US: no-good all-seasons as STD. Steering precision?
I will, however, cheat and by winterwheels from outside source - at half price. It is possible to have tirepressure sensors (pirate), that will- after calibration - work on the vehicle, but I don`t think I will bother.
