New and used 2026 GMC Sierra 2500 AT4 trucks for sale near Mead Valley, CA

I had probably the easiest, most hassle-free experience buying my new truck. Kaylynn was very accommodating and found my perfect truck. I couldn't be happier!

Adam Miller in the service department is the best! He is always very friendly, and makes sure my vehicle and I am well taken care of. It seems that nothing has changed at the dealership since it was sold. I am very happy about this. Thanks again for the great customer service!

Temecula Valley Buick GMC is a great auto dealership. Service department was excellent and Mike R., is always great and explains the service jobs in detail. Awesome job experience and would recommend them to others.

Good quick service getting my new towing mirrors installed. Also cleared the check engine light. Steve Pacheco did a great job making the repair happen.

On April 6, 2023, I took delivery of a 2023 Yukon Denali Ultimate, which was a SUV that I ordered, equipped the way I wanted it. John and the entire sales staff were great! I have purchased/leased 4 other vehicles from this dealership and have always been treated well. If you want to avoid all of the seemingly normal drama that goes along with walking into a dealership, you need to try this one - you'll be pleasantly surprised.

Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

Christopher was very helpful and professional. Make the experience so nice and smooth. I will refered anyone who will be looking for vehicle, of the brands that he sell.

Dealer add ons are extremely high, we were able to work on some of those numbers. Still high after bargaining, but I agreed since I wanted this truck. When Mariah came back with financing option, I come to find out that we can't finance outside, it has to be their financing or pay cash! Can you believe this? After everything done with salesperson, had to wait for finance. Sat for over an hour &1/2. Employess kept walking in & out of finance office, some eating, while customer just waiting.

Staff was friendly but i left without being able to have my app hooked up to my car and I was looking forward to that feature

I had an amazing experience yesterday at Tustin GMC & Buick with Seth R.. I called him the night before to ask about the Sierra EV 2025, and he got right on it! We got the deal done in minutes, charged up the truck, and it was waiting for me to pick it up the next morning because I couldn?t make it that evening. This dealership is incredible! I usually buy luxury vehicles, and the service was just as great as when I do business with Porsche or Land Rover. George in finance was nothing short of amazing as well. The management is doing an incredible job keeping them going because they have such a great team. Every turn was met with a smile, and even in workout clothing, I felt like a valued customer. Thanks to Seth and George, this dealership is now my new pick-up truck home, and I?ll definitely be buying my pick-up trucks through Tustin GMC & Buick in the future.

Experience was excellent! Everything was so smooth and easy! We are so happy with our purchase! Highly recommend Danny from GMC! Customer service was on point!

Mark Christopher GMC is an amazing Auto dealership. No sales pressure and terrible prices. Johnathon Villa was an outstanding salesman that helped us get a 2022 Canyon Elevation. He took extra steps to help us find the perfect truck for us. We drove over an hour. And so glad we did. Highly recommend. And I want to say thanks again to Johnathon for making the experience great.

My experience at the dealership was excellent from start to finish. Abraham greeted me right away, took the time to understand what I needed, and answered every question with patience and detail. The entire process was fast, smooth, and professional. I truly appreciate his outstanding service and the overall efficiency of the team.
