I recently purchased a used Porsche Boxster that needed some work. When I brought the car in for service. I was greeted by two very friendly people. I spoke to Ken (owner) and I immediately could tell I went to only place to service my Boxster; Ken is extremely knowledgeable with Porsches, and I assume all of the other European cars his shop works on. A few days later I went in to pick up my car, I was again greeted by Ken and his associate, I think his name may be Mike, and again top-notch service. Mike explained all the work that was done to my car and now pay the bill. I have to say, with all the work that was done, I was expecting a much larger bill than I was presented with. I will say to everyone reading this post, in the Tri Valley area, for excellent, reliable maintenance on your European car, take it to SAS German Auto. I promise you will be happy you did. It is worth the drive to Pleasanton. John Michaelides
