1) sorry to hear about your troubles
2) Moritz sucks never seen so many wrecked cars sold by a BMW dealer before or since.
Just like Ferrari, good brand but the dealers are the ones screwing up their image. Autobahn BMW has really worst rep of all dealers here. Maybe time you cut your losses and move on to newer car or different brand?? Whatever you end up doing wish you best of luck. I'm on BMW #3 and couldn't be happier with them. I stick with BMW of Dallas for all service have yet to disappoint me.
