Fellow Mercedes owners there is a great shop in Fayetteville, just outside Ft Bragg called LANE AUTOMOTIVE. They are experienced and real fair with pricing. I had an SL500 with a water pump issue and electrical problem and they were fast, courteous and extremely fair on the prices! Their experience in European cars is apparent, and their egos are not inflated because of it (if you know what I mean!) Try them out when you are in the area. They do regular service too.
