I posted post #5 above.I drove two hours to Sun Motors to get them to inspect and repair in six hours what my local MB service center took 5 ½ weeks to diagnose and then screw up. They were courteous, communicated clearly, answered my technical and dumb questions, efficient, knowledgeable, reasonably priced. They were able to give me a ride to a diner or motel or car rental if I needed. There is a car rental facility within a mile if I needed to leave the van for a period of time. They got me on the road so I could come back in a week when other parts came in and have all the work completed. I was skeptical at first of having to drive far for good service but Sun Motors was worth the trip and I will continue to drive out of my way to do business with them.
