Shoutout to John for his incredible service! Seriously one of the best service experiences I’ve had. He was welcoming, super organized, and kept everything moving even when it was busy. Communication was on point, no attitude, no stress, just solutions. You can tell he genuinely cares about customers and runs a solid service department. 10/10 recommend.

Had a very good experience purchasing a previously owned truck. Starting with our initial phone call, we were connected with Alan who took the truck in on a trade (and I think sold it originally). He answered our questions and made us feel confident to travel 107 miles to see the vehicle. Our confidence continued to grow during an inspection and drive. Alan was fair to deal with and as someone below said, "was very honest and kept it very simple. Also transparent with all the numbers from start to finish. No dickering back and forth with 'My manager'." Kudos also to Jason. Paperwork was taken care of quickly, and never once pressured us to by some "protection" or warranty we didn't want.

We stumbled across Coffman GMC looking for a truck to tow our new camper. We were looking for a specific 2026 Sierra 3500. However, I had my dealerships confused. Best mistake we ever made. We ended up finding a great 2024 used truck. Rudy was so helpful and made us feel at ease. The process was easy and not stressful at all. We came back the next day and met with Jason in finance. Once again, a super easy and calm process. We asked a lot of questions and kept people past closing. We were never rushed to finish up. There are a few things that are different when owning a diesel 3500 truck from a 1/2 ton. The team at Coffman helped us understand those differences especially Rudy. Rudy also helped me find a safety lane facility to get the truck inspected. If you are looking for a GMC, check out Coffman. Down to earth, no hard sell, nice people.
