“Dennis is a LIFE SAVER!!!!! I have a 2006 GMC Sierra 3500, and I was stuck in South Dakota with a bad BCM. The truck would start and then turn off after a second. Went to a local shop there and they replaced it, but programming it wasn’t working. Got the truck started and decided to take it back home to bozeman while not turning it off. Called Diesel Pros, told them the problem and they told me to call Dennis as Dennis is a GM master tech and he would know how to deal with it better. So when I got back, I headed to Dennis shop and dropped off the truck. Let me tell you all, Dennis is the freaking king of GMCs. He identified why the new BCM wasn’t working correctly because the lock signal housing in the ignition wasn’t sending a signal to the BCM. He got that replaced and BOOM 💥, the truck is starting normally. This was a very complex problem that only an expert in that type of truck would be able to diagnose correctly. I will never take my truck anywhere else, it will only go to Dennis. Not only is he an expert with GMCs, but he’s a standup honest guy who cares about the quality of work he does. He explained everything in detail on what he was doing and why he was doing it which makes me as the customer feel valued and cared for. While some shops will gouge you on costs, Dennis is super transparent & fair. If I could give a million stars of rating I would, and that’s why I will see him again in a few weeks to get some minor things done. Thank you Dennis, you’re the man!!!”
“Had the driver door on my work van, a 2025 mercedes sprinter get hyper extended when it was caught by the wind. Brought it here and while Steven was looking at it, he was about to repair it enough to stop it from causing more damage till it can be repaired completely. Will definitely be recommending him to everyone, will be back”

“I brought my truck in for bodywork that was caused by a hit and run. These guys are amazing! Exceptional service. I was able to get in right away, great customer service. They were friendly, fast and best of all they cleaned the inside and outside of my truck when I picked it up. They also kept me in the know the entire time and worked with my insurance so I didn’t have to. I can’t recommend them enough. Thanks again Manhattan Crash Champions, you have my business forever.”
