I have been a customer of Advanced Autowerks for awhile now. I have always found them to be efficient and effective mechanics. My car is older, but it runs better than ever. I am always happy to drive after then have worked on the car. It runs so much smoother. They also give me heads up on what work is coming up so I can plan. They are easy to work with and really competent and knowledgeable when it comes to VW and Audi and they may work on other cars too, not sure.
