Used GMC Sierra 2500 trucks for sale near Carol Stream, IL

The entire experience was easy-going. From initial contact with Justin in sales to the relaxing atmosphere of the dealership. Justin was friendly and helpful through the entire process. Would highly recommend Fair Oaks Lincoln. Ask for Just

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.

Eduardo Del Rio helped me buy my ford explorer and made sure it was in my own liking

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.

Big thanks to our salesman Brian for excellent service. Very through and he,Paul in finding the right vehicle for us. Prompt courteous service. A very satisfied customer. Highly recommend Woody and ask for Brian.

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.

Buying my Camaro from Castle Chevrolet in McHenry was an outstanding experience from start to finish. I worked with Eric Loredo, who set the tone by doing a full virtual walk around and video of the car before I arrived, answering all my questions in real time. When my wife and I landed at ORD, the car was spotless and ready to go. Finance Manager Mike Lazzara had all documents sent ahead so I could DocuSign, making the delivery quick and smooth. Sales Manager Matt Knudson, GSM Jerry Spanier, and Andrew Sytsma (who wasn’t my salesman but still took time to chat and share product knowledge) all played a part in making this one of the easiest purchases I’ve ever had. The team knew my previous car was totaled in a tornado, and they went above and beyond to make this out-of-state transaction simple and stress-free. Eric and the entire Castle team reminded me that buying a car doesn’t have to be a battle. I would absolutely buy from them again.

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.

My first experience at this dealership will definitely bring me back. We are so happy with our purchased! We had Alex Alverio from Sales, he was very professional & helpful, has awesome customer service & we highly recommend Alex. Thank you so much and keep it up!

Steve was a great salesman and helped me find the car I was looking for with everything I needed! Steve and his team were a big help and I’m looking forward to enjoying my new Tahoe. Thanks Advantage!

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.

If you’re on a market for an ultimate driving machine. BMW of Elmhurst in Illinois is the ultimate dealer to get that machine. Michal is THE guy to see.

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!

Thank you to the service team for your getting me all set for my roadtrip!

What a great experience at D? Arcy Buick Dealership in Joliet IL. The staff was friendly, honest, and made the whole process easy. Ray our salesperson went above and beyond. I love my new Envision Sport and would definitely recommend D?Arcy Buick and ask for Ray!!

Great customer service, Alex helped me out with financing ! I recommend them if you are looking for a reliable car and good financing options!

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!

Jon David is an asset to your company he’s a gentleman and a scholar. He put a deal that I won’t forget, and I won’t forget him. My son was very happy and he treated him with courtesy.

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

I bought a 2011 VW Routan from Auto Gallery. Steve went above and beyond to make my car buying experience painless and easy. Great guys to work with. Will recommend to friends and family.

Worked with John B for a new Bentley. He was quick and efficient, answered all my questions and the car is in mint condition. Car was fully serviced and I love it

Eduardo gave me an amazing service at the dealership and helped me find a car.

Awesome service from Huntley ford and it's salesman Rob specifically. Huge selection makes car shopping in one place easy and convenient!

I recently purchased a 2026 GMC 2500 Denali, and it has exceeded all my expectations. The truck is powerful, smooth, and built for both work and comfort. The luxury interior, advanced technology, and attention to detail make every drive enjoyable. Towing capacity and performance are top-notch—perfect for heavy-duty needs without sacrificing style. A huge thank you to Tony Gullette, who was an outstanding sales professional. Tony made the entire process easy and stress-free, providing clear answers, honest advice, and exceptional customer service. They went above and beyond to ensure I got the best deal and left completely satisfied. If you’re in the market for a premium truck, I highly recommend the GMC 2500 Denali and working with Tony. You won’t be disappointed!

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!

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside
