CMC Diesel did the BEST work I have ever had done on my 2000 F250. The alternator broke and left me stranded on the side of the road by Columbus. My truck was towed to their business while I continued on to Bozeman. Clay kept in touch with me as he worked on the truck AND took the time to go over the engine with a fine tooth comb. He and his team found a couple other issues (including a worn timing belt and messed up water pump) that were going to cause me grief in the near future. When I came to pick up my truck, he showed me all the work he had done to it as well as the worn parts--I knew he was not just 'adding on another thing' like so many other places I have taken the truck. He was also honest and clear about continued maintenance and how to prioritize any work I may want done in the future. I will definitely bring my truck back to CMC Diesel in the future--the drive from Bozeman is worth it for honest, reliable, friendly, educated, and trustworthy service.
