Used GMC trucks for sale near Thornton, 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.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I was very fortunate to have the greatest salesman, manger, General manager and finance director in the business assist in my purchase. Thank you "Coach" for all you do for me and the family

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

JSON helped me out today t south oak and personally edge my vehicle thank you

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Started inquiring via dealership messages and after 5 messages was able to secure a great deal. Best deal out of 3 other local competitors dealer offers. Greeted by Jennifer Z. at dealership and finalizing paperwork went seamless. End to end I was out the door driving exactly what I wanted and with the terms I felt were fair across the board. Highly recommend with my personal experience!

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Great service - knowledgeable and friendly staff. Took the time to explain everything and make the process seamless. Look forward to doing business with them again.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Wonderful experience at McGrath Lexus ! Very happy with their knowledgeable team , beautiful and well made cars.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Very quick, good communication . Honest. Feel like you can trust them to be fair. Happy with results. Will return for other needs if they arise in future.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

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.

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I am satisfied with my visit. I do think more thorough inspections should be done. My headlight was out and I knew this before the visit, but on the checklist it was marked as good. I love the cookies that are left after service visits as well .

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Gerald Griffin was awesome in assisting me with purchasing my new car. Since then he has been occasionally following up to ask about the car and everything. 5 Star service

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

I worked with Luis Torres, he was so helpful and informational. He made the intimidating process of buying my first car enjoyable!

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I have purchased a Defender and a Range Rover Sport from South Shore and the experience both times was stellar! Jordan, my salesperson, was terrific from start to finish. I will definitely purchase from them again and will happily send my friends and family in for a car. A+!

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

The staff is very experience and professional. The estimate for repairs were in line with the services. I compliment the facilities with free coffee, water and soft drinks.

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

I could not get a decent car any were CarMax put me back into the drivers seat i will recommend CarMax to anyone Andrea and his team in Tinley Park are truly number one in car sales . Marcel Potvin.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Bought 4 cars from them through the years. Great service and honest establishment. Will keep going back!

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

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

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Chris Jeeninga was on top of his game and ready to assist me in my search for a car. Although new to the car selling business, and youngster just starting out his career, he was kind, courteous, and helpful. If he didn't know the answer, he admitted he was learning but got us to the right information and helped us to a decision on our car purchase. Keep up the great work.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Sold a 2018 Honda Civic 2 dr coupe on Friday, 11/14. Alex was absolutely great. They purchased the automobile for exactly what they had quoted. We will never sell or purchase with any other dealership! They were fair and honest which is not true of many other dealerships. Would recommend whether buying or selling. Do not waste your time with anyone else.

Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!
