New and used 2025 GMC Sierra 2500 AT4 trucks for sale near Marsing, ID

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Ryan Sigman was an amazing, honest and personable salesman. It was a very enjoyable transaction. We loved his honestly. We appreciated his help!

Sean and Jamie were incredibly helpful. Initially I was looking for a car they were not selling but they helped me anyway, ending up in a sale for them, and a great deal for me with a car in my budget. They were really great to work with, transparent, showed me all my options and gave me time to make my decisions. Sean in finance was great to work with explaining things very thoroughly. Really appreciate the professionalism from these gentleman.

I always take my truck (2016 Chevy 2500HD LML) to Dennis Dillion for service and repairs. I recently had my Alternator replaced under my extended warranty and Brandi Jacoby my service representative processed the claim and received approval enabling them to complete the repair quickly. I am back on the road and my truck is performing like new I would always recommend Dennis Dillion for anyone who appreciates a professional and kind service department.

The service visit was great, the truck seems to be running fine. I certainly appreciate your consideration and your team's attention to my concerns. Thank you!

Tye was our sales rep and he was Awesome. Very knowledgeable and patient. Didn?t try to push anything on us and was able to answer all of our questions. We had chosen the AT4X and it is an awesome truck. We had made a mistake and made assumptions about the towing capacity and it turns out, the AT4X does not tow as much as we originally thought. We quickly realized our mistake and Tye and Reggie where able to help us resolve the issue with out taking advantage of us, for that, we are extremely thankful and will be returning to them when we are ready to purchase a 2500. So if you do go with Dennis Dillion, ask for Tye. The only thing I had an issue with was the financing portion. There are some things that did not make sense, extra fees and having to use their affiliated banks to keep their incentives. Make sure you are asking financing questions if you do plan to finance a vehicle from them. But again, Tye helped us get through all of that even that part of the experience was painful.
