First, if you are in AZ, what dealership did you get the car from, are you in Phoenix or Tucson? How long ago did you purchase the car. If this was a franchise dealership, I.E. a BMW of Scottsdale, Don Mackey BMW (Tucson), then you can go back there and talk to the manager and show him the report and explain your situation. If that gets you nowhere, I would call BBB and file a lawsuit in small claims court for fraudulent sale and whatever else you can stick on to that, maybe call a few lawyers in your area and ask for a free consultation. Finally, call local newspaper and or tv station (KGUN 9) in Tucson actually has a department dedicated to stuff like this called KGUN 9 On Your Side. But I am sure if you are in Phoenix they too wil have something like this. Tell them the story and try to coerce them into doing an interview (this will work even better if the dealership tells you its your fault) Local news companies love scandals like this. Finally, you can try to find a way to get a hold of BMW USA and chat with or email someone there regarding the situation and complain on that specific dealership, alse threaten lawsuit and going public. In this HORRIBLE auto market no Dealership/Auto Maker can afford to have even the slightest bad publicity. Hope this helps.
