Used GMC Sierra 2500 AT4 for sale near Dupo, IL

Gus and his crew were amazing. I bought this pickup off the internet, and they picked me up at the airport and 1 hour and 20 minutes I was headed home.

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.

I always get great customer service from everyone at Laura Buick. My go to guy is David Day. They always do a great job with any issues with my car.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Great experience. Jimmy was great and answered all my questions. love my new Yukon XL 2025. I would definitely recommend Jimmy and this dealership to my friends and family.

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.

Very satisfied. Colin went above and beyond to help us. He was so helpful. Very knowledgeable about all the cars we test drove. Would ask for him again next time we are ready to buy.

Adam Killian and Randy were awesome! This has been the best experience we’ve had!

As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!

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!

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!

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.

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

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.

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

The customer service at Dave Sinclair Buick was fantastic! They had a lot of work to do on my vehicle. The work was flawless. The level of communication during the whole process was superb. Eric in the auto body shop showed what excellent customer service should look like. I cannot thank them enough for the level of service the team provided.

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!
