Used GMC Sierra 2500 trucks for sale near Millstadt, IL

Easy process. Dmytro was very helpful and accommodating. Follow up was timely. Found the car I wanted online, submitted a request for information, received a call back immediately.

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.

Colin was beyond great I would recommend him to anyone. I’ll definitely be back because of him. I couldn’t ask for better service. Thanks again

IT was a very enjoyable experience. I will truly recommend you all to family and friends. From the beginning to the end of the process was awesome.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Luke Ramos was an excellent salesman. He stayed after hours to ensure I would get into the vehicle I chose. They also found the right lender for me to ensure I was financed and left same day with the vehicle. The entire team went above and beyond in valuing my trade, selling the vehicle, and ensuring my happiness. I cannot say enough good things about this dealership!

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

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.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

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 found the exact car I was searching for and this dealership was above my expectations during the buying process.

Josh Roseke was very accommodating, professional and accurate. He ensured the experience was painless and efficient. The dealership should be proud to employ an associate of his caliber.

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

We had the best experience with Autocenters Nissan. Our salesman Nikolas Kennedy was amazing. He worked with us to get the best possible deal that worked for us. We love our new Nissan Frontier ❤️ We highly recommend Autocenters Nissan 😊 Robert Smith

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.

The paperwork took some time but now I see why. We are very happy with the car but a few issues came up....brake fluid was low causing the brake pedal too pulse. A quart too much engine oil. Windshield fluid was empty.

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!

Kelly is awesome helped me trade my xxx for an amazing truck. Love it thanks

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

I had a good experience buying my new truck through Laura. John Touchette was a great salesman throughout the process. Laura provided financing that got me the truck i wanted at a fair price with good interest rate! The whole signing and pickup at the dealership took about an hour. Thanks Laura

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

Josh Roseke, my sales rep was fantastic! He found me the exact SUV package I wanted and I love it!!! Michael in finance was great too!!

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!
