Not very good. My car was kept for nearly 4 weeks and I had a variety of services offered that were not needed or asked for. My original request was for a engine diagnostic and battery. I received a new valve body for transmission and a valve cover assembly(which was never in need of repair. When I picked up my car within 10 minutes of driving a drive train malfunction light appeared on dash. I had my car towed to nearest independent shop and the battery was replaced along with new spark plugs. I spent $2000 with BMW and my car was running aweful. I spent $500 with independent garage and it runs great. My advisor was aweful and not knowledgeable along with mechanics.
Management did not appear to concerned as well. They don't know how to fix their cars. Last Beamer for me.
