Used GMC Sierra 2500 trucks for sale near Deerfield, IL

We recently purchased a Porsche Macan from Napleton Maserati of Downers Grove, and I can’t say enough about the exceptional service we received from start to finish. Even though we’re located all the way in Seattle and never saw the vehicle in person before buying, the entire experience was seamless, trustworthy, and surprisingly personal. From the very beginning, Orsie on the sales side went above and beyond — answering every question promptly, providing detailed photos and information, and making us feel confident and excited about the purchase. His honesty and commitment to service were truly refreshing. On the financing side, Alex made the entire process smooth and straightforward. He explained everything clearly, helped us understand all options, and kept things moving quickly despite the distance. What impressed us most was the trust and transparency every step of the way. In an age where buying a car sight unseen can feel risky, they built an experience grounded in professionalism and care. We would highly recommend Napleton Maserati of Downers Grove to anyone — no matter where you're located. They proved that exceptional service and trust can travel any distance.

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.

Fast and easy buying experience at Huntley ford! Rob knew the products well and got us into our leaf quickly and Frank got us in And out of finance just as fast!

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 Audi Q5 was driven to look at a warranty covered repair, it was shifting roughly from Park to Drive. It took about 3 days to check everything out, reset the computer for driving more smoothly and make sure all warranted systems were in peak driving condition. They fixed everything very well and submitted warranty covered conditions. Also the Service Specialist, Kristian, set me up with a 2026 Audi Q5 loaner. My whole experience with Audi Westmont dealership has been top of the line. I send kudos and praise to all the staff that assisted me and fixed my car properly. I purchased my Audi Q5 at Audi Westmont and will continue with all my servicing there. I also will purchase my next Audi at this dealership. High praise for all they do for their clients@

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.

Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.

Violeta and Tim did great job with whole process Very transparent and very accommodating and was able To get me into the car I wanted and even fed us lunch highly recommend Violeta as sales person and countryside nissan

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 were so happy to have been helped by Elijah he was truly so patient with us as we were getting a bit nervous on not getting the vehicle of our choice. He was truly helpful all the way to the end. He was very informative about everything highly recommended him for any purchases at Dodge Ram. He's the man. Thank you Elijah you are truly the MVP hands down.

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.

I had a great experience at Golf Mill. Jimmy took care of me and got me into a new lease. Thanks!

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.

Purchased my 2025 Bronco today and the process couldn’t have been more easy. Dylan was our sales rep. He was absolutely amazing from beginning to end. The manager came over to introduce himself and was very personable. The gentleman who did our financing was the absolute BEST! I have never had a car buying experience as easy and as fun as I did with Kunes. I rang the bell and they added a big red bow at my request. We were treated like family. I was overjoyed. Didn’t feel like a car buying experience felt more like a gathering of family and friends. Thank you Kunes

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.

Great customer service. Repair was done quickly and service manager stayed in communication through the whole process. Never had a issue reaching the service department.

We've worked with Tony before & he is very knowledgeable & knows just what we like.

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!

Frank was friendly and helpful. He look up my records to make sure I was not receiving and paying for unnecessary service. He provided a coupon.

very good service nice place to wait. Nice people no problem with anything would tell my friends and family to go there. even when I first call the where nice

From the moments I got in the dealership until I left I was treated very nice and very welcomed. I looked at Lexus RX and end up buying it because I felt comfortable and car is clean with good competitive price. Very recommend

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Compré un carro muy bonito y muy amable el personal súper recomendable a todos

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!

Was a pleasure doing business with these guys. Gorgeous showroom with an amazing selection of cars. True enthusiasts here. Got a great price on my car, they offered a fair price on my trade. Were super up front on all details of the car and the deal. Fast and efficient. I look forward to buying again - these guys are more like a fine automotive concierge service than a dealership! Keep it up fellas!

I have never bought a car online before let alone bought a car without even seeing it or driving it. I saw a Bentley Flying Spur for sale at Chicago Auto Gallery. I called and spoke to a salesperson named Steve. From the first hello on the phone until we closed the deal and the car was shipped to me Steve was fantastic. He did everything possible to ensure that I was satisfied with the car and the deal. Now here's the extra part that I was even shocked at myself. Once I got the car, I drove it and after 5 miles some of the lights came on such as check engine, ride height, traction control and ABS. I was initially immensely pissed. I called Steve and said you might want to get ahold of that driver who delivered this car and tell him to take it back. Steve suggested I take it to a certified mechanic near me and have it looked at to see what was the problem. Apparently when one light goes off, it triggers more lights to activate. I had it looked at and to fix the car right it was going to be over $3000. Steve took care of it and the dealership paid the whole bill. In my mind that was the most solid thing to do and he did it. He could have argued and tried to avoid it or said no, you bought it, you fix it. They did not do that to me. I'm in Pittsburgh and they are in Chicago. I know I had rights and could have just sent it back but I wanted that car and they fixed it for me. I appreciate everything they (Steve) did for me and I would definitely purchase another vehicle from them. Thank you again Steve and Chicago Auto Gallery.

Great Prices, staff and selection of vehicles to choose from! Thanks Jose for an amazing experience

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.

The dynamic duo strike again! Corey and Tito came through as always to meet my wants, my needs, and my budget! Always professional and knowledgeable and willing to go that extra mile when needed. I couldn?t ask for a more dedicated Team!
