I accidentally put regular unleaded gas in my Mercedes diesel SUV. Ughhh...I had it towed to the local Merceds dealer. I was told that it was totaled. Or, I could pay 17 K (17 thousand dollars) to have the engine drained, replaced, etc. .very upset, I googled who else works on Mercedes, and I called German Motors in Las Vegas where this happened, and they answered their phone. They arranged to get my Merceds towed to them the next morning. By the next day, it was taken care of, restored. It was 1,500 dollars for the entire repair including the tow! It was not totaled nor did anything need replacing as I. had been told by Mercedes. The SUV runs great...I really, really recommend this place.
