Used GMC Sierra 2500 AT4 for sale near St. George, MO

We love our new SUV! Kelly was great to work with! She is a straight shooter.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Bruno and Oscar were great to work with! Very knowledgeable and helpful. Overall a great experience!

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Wonderful experience! Laura Buick didn?t disappoint as usual! Repeat buyer and will do it again! The staff and facilities are first class! Our salesman Cory Sperry was phenomenal!

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Conan Thomas was my service advisor and the service was excellent. Took care of everything and made this service call as easy for me as possible. I will always go back to Sapaugh.

Justin was easy to work worth, made buying the 2026 truck quite painless. Very knowledgeable. He was very prompt in returning my phone calls. Would buy from him again.

Great service from TJ my service representative. He kept me informed throughtout the process. Even calling the warranty company to see if the repairs were covered.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Josh Roseke was the salesman I had and would highly recommend him to others. he was very helpful and patient with my questions and choices.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

I met with Dave Fisher, he made me feel very comfortable from the beginning all the way through the whole process of buying a used vehicle. No pressure, no stress. I was very happy I decided to go to Sapaugh GM Country. Thanks Dave for making the process and easy one

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Love this dealership! The new location is wonderful - I send my family here. My brother bought a car, and loves it!

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.

Mark was great to work with, explained all the features and quirks that our car had. Would definitely recommend. Thanks Mark.

Excellent service. Approved immediately. Thank you, Peter, for your help! There are many options to choose from.

Justin Fuller was my sales rep and my experience was incredible. Everything from the process to order a new car, the trade in value, financing, etc. was smooth and Justin kept me informed along the way. Would highly recommend to anyone in the market!

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.
