Used GMC Sierra 2500 trucks for sale near Belleville, IL

It was the best experience! So fast and easy! Ethan was great to work with! I will definitely be back to buy my next car!

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!

Worked with Chris Phillips at Weber Ford. Had an amazing experience. Great deal and no pressure. Will be back for my next vehicle purchase

Unfortunately Steve Schmitt didn’t have a Jeep Grand Cherokee that I was interested in. Their response time to my Jeep inquiry was very good.

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.

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!

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!

We have been purchasing Ford vehicles for over 40 years and were again very satisfied with our current purchase. Brett Bergman at Sunset Ford in Waterloo, IL made the transaction very easy. His smiling and friendly personality made this a pleasurable experience. He was very knowledgable and answered all our questions. We then met with Mike Rich who was also very personable and worked with him to seal the deal. Mike Carr handled the paperwork very timely and professionally. Sunset Ford not only is great to deal with in selling you your vehicle but is there for you with outstanding service after the sale. It's great to be a part of the Sunset Ford family!

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!

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.

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

We love this dealership! Nick Karateew has helped us with several vehicles over the years, and it’s always a pleasant experience. He is knowledgeable and takes his time explaining everything. Alex handled our paperwork and made it so easy. It was enjoyable getting to speak with him. I will always recommend this dealership to everyone!

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Nikki was extremely professional and knowledgeable about the trucks. The buying experience could not have been easier, and I never left South Carolina! My new Denali Ultimate gets delivered today at 5!

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.

Salesman Chad Bade and Finance Manager Richard Lomara were awesome! Everything was handled in a professional manner.

I spoke with Tra Farrow recently at the Alton IL. Location. I was completely honest with him. He ask where I was thinking I wanted my payment to be monthly. I give him my response. I was buying a pre owned vehicle. I bought a Dodge Ram regular cab. He also was completely honest, respectful, of my request. He said he would see what he could do. After talking it was clear that we could complete the sale. I have always purchased my vehicles from private owners. This is the first time I used a dealership. I have this dealership and Tray a five star rating. While I realize it is difficult to get it give a business a five star rating. It was easy to give them the best possible rating. Everyone whom I came into contact with during my visit was outstanding. I was overwhelmed at how easy it was. This business could not have done anymore to change my opinion of dealerships. I know all things do not end this way. If you are in the area of Alton IL. Please give Tra and the staff an opportunity to serve you.

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.

Thank You Chad Sigsworth for your help with the purchase of our used car! You made us feel like your own family, no pressure to make the purchase only the truth! We are very satisfied with our Escape!

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.

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.

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.

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.

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.

Great group to work with. Everything was straight forward with no hidden fees. Definitely recommend seeing the folks at Steve Schmitt for your next purchase. Ask for Brandon Fisher.

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.

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
