I found the Mercedes-Benz dealership in Flagstaff to be wonderful to deal with. My Mercedes Sprinter van wouldn't start and I had it towed to Flagstaff. The battery was weak and they replaced it. Batteries for those vehicles are not cheap, but they completed the work quickly. However, the problem persisted and I had to bring it back it. Every step of the way, I was treated as if I was their only and most cherished customer, going out of their way to help in whatever way they could. The second time, the van was in for a few days, as they were not sure what the problem was, and were testing it and trying out various possible fixes. I was given a new Mercedes as a loaner car for the duration. Every time I called I got a patient, detailed update. There had been rodent damage and there was a possible computer issue. When they returned the van to me, in case the problem still wasn't fixed, I received a huge pre-Christmas surprise. The bill was for $0, even though they had spent many hours trying to diagnose it. Stephen even helped me spray the engine with peppermint oil and install a flashing light to discourage further rodent damage. The guys in sales were as helpful as possible too - driving me to pick a rental car the first time I was towed and arrived on a Saturday when the service department wasn't open. I highly recommend this dealership for service!
