Used GMC Sierra 2500 trucks for sale near Millstadt, IL

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 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 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.

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.

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.

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'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.

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!

Today we went in to Sunset to look for a new truck for me. Unfortunately it was not in the cards dealt to us. So my wife and I decided to look for a new car for her. George was our salesman and he was fantastic. He was very knowledgable about the cars and was very friendly to my little boys He was also very patient with us as we tried to figure out a budget and what we can afford. Finally we were set on a 2016 Escape. I test drove it and even for a big guy like myself, it was a fantastic vehicle. We went back in and crunched the numbers and came up with a deal. The finance manager Mike was again fantastic and worked his magic to get a payment within our budget. He has earned the Nickname Magic Mike from me. I am 125% satisfied with the staff at Sunset Ford. This was my second car from there and I am looking forward to buying my third. Hopefully it will be my new truck.

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!

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

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.

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.

Kyle was a pleasure to work with. He understood what I wanted and worked with me to make sure I got the right car. I highly recommend finding Kyle and working with him with purchasing your next car. I will be going back to him when we look for a car for my hisband

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

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.

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 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

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

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!!

When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

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.

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!

Shawn did a great job working with us to get us the terms we wanted.
