AZ Bimmer Works is great! I purchased my E46 M3 last year from a person in CA and wanted it to get inspected to see what maintenance was required. Upon arrival, Nick and his staff were very nice, not pushy at all, and provided details of the work that needed to be done to the car. They never tried to sell me over on things (unlike the stealerships), and if I had a concern, he would actually break it down for me, or show me on the car itself. Their prices are very good, and the quality of work is top notch.
If you live in the East Valley (or even the West Valley if you dont mind the distance), I dont see how you could ever go back to getting ripped off by the dealerships after trying out AZ Bimmer Works. Their prices are cheaper, the quality of work is way better, and they are just good people who want to give BMW owners a fair deal.
