The people at MB are some of the best that I have found in the North Charlotte/Lake Norman area. I had my valve cover gaskets replaced at another independent MB shop while I was out of town on a Friday and by the time I got back to the Mooresville, NC area that evening, my check engine light came on and the car was running rough. I looked online that night and found this shop was open on Saturday morning. I took my E55 there on Saturday morning when they opened and Tony (the owner) quickly worked me in for a diagnosis. The tech (JP) quickly found the issue pertaining to a hidden vacuum tube that was not reconnected from the previous work (at the other shop) and he reattached the tube and I was off and running. I have since been back there for some other maintenance work and these guys deliver quality work at a fair price with experienced MB technicians. Big Dan is another senior tech there and he is awesome and brings a tremendous amount of MB expertise and "know how". Their overall experience with AMG models made me a happy customer. They are now on speed dial for when I need them again.
