Reliable. I am the original owner of a ’99 Mercedes wagon that I want (need) to drive for a very long time. Several months ago I had a 100,000 mile maintenance service and a long list of small issues resolved by this shop. It was not cheap, but they fixed everything to my satisfaction and had the car ready when promised. I have not had any more issues (they guarantee their work), and I plan on continuing to use them. Note: I am on a budget and take time to research shops and mechanics. In this case I believe that you get what you pay for. If that changes I will update this review.
