At Sargent Auto and Diesel Repair in Grain Valley, MO, we're passionate about servicing GMC vehicles. GMC is an American division of General Motors (GM) that primarily focuses on trucks and utility vehicles. GMC is a name you trust, and strength and reliability are just two of the reasons why you chose a GMC automobile. But even the most reliable of vehicles need service from time to time. Your life depends on the hard work your vehicle does; and when your GMC needs service, you need the help of a mechanic you can trust.

5-star review by Adam Kramer

"I went in for an oil change and they found a few other things that needed attention. These were things that the last folks ( Chevy dealership) should have found but didn’t. They were problems that would have caused serious problems later. The mechanics and owners here worked to get my truck taken care of fast and efficiently. They care about the people that bring their vehicles in. I won’t go anywhere else in the future. Great job and thanks so much."

"Great group of guys in here. I was in town for work when my truck broke down. They got me in the next day. Great customer service. I talked to several dealerships in the area that were saying it was a week turn around. They had me back on the road in 24 hours."
