Premier Auto Service
While it kills me that they are not open on Saturdays, the customer service, honesty, and fantastic mechanics more than make up for the schedule. For example, I had sensors replaced recently on my M45 and they when bad after about 1.4 years. Even though the warranty on the parts expired after 1.0 years, Premier did the work for free. I have never felt like they are trying to rip you off and do extra work for no reason. Highly recommend them.
