Used GMC Sierra 1500 Denali for sale near Wheeling, IL

Ross in Service is one of the best in the business! I have been to a ton of dealerships over the years and his attention to detail and professionalism stands out by far. He also gives that gold star service to everyone that comes in. Service was super professional and speedy! Ross was more than helpful!! I had a great experience and will be back soon!!

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

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.

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 !

We recently purchased our first Lexus SUV and worked with Dylan K. He was incredibly knowledgeable and a huge asset in the car shopping process! I appreciate the great communication and extra efforts he went to on our behalf!

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

Service Advisor, Nicholas Moore went above and beyond. He asked probing questions about the issues I was having and he did a deep dive into my car history and found it was a known software issue. Bing, bang, boom! I was out in no time with my troubles behind me. I will recommend Nicholas anytime.

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!

Bought a car on Wednesday night noticed the brake light was out. Told me to bring it back on Monday and they would take care of it. Did the oh I am in a cabin filter and even filled it up. Will shop again.

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.

Autos of Chicago made the car-buying process simple and stress-free. The staff was honest, patient, and very helpful in answering all my questions. The vehicles were in great condition and priced fairly. I never felt rushed or pressured, which I really appreciated. Overall, it was a smooth and professional experience, and I would gladly recommend Autos of Chicago to anyone looking for a dependable used car dealer.

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.

I was looking for a specific car that was at this CarMax. Problem was that I live in Minnesota, not Chicago and would have to traveling a great distance for a car I had not seen other than in pics, potentially risking wasting a great deal of time and money. I had to trust Jonathan, my salesman, to tell me the condition of the car where the pics could not. He was completely honest and the car was exactly what he said it was. Between Jonathan and Adam, the sales manager i was able to close the deal and drive back to home within an hour. I am completely pleased with the car and 100% satisfied with the dealership. I guess you can trust a car dealership. I did and they did not let me down. Thanks guys.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

Joey Dalporto assisted us with our purchase of a used Buick Cascade. He was very approachable and helpfully answered all our questions. It was a great car-buying experience.

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. :)

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.

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 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!

Rudy was a good sales man! I would recomend this dealership to friends and family

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!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

I had a great experience buying a used 2016 Hyundai Genesis. The whole team was polite and courteous. They also have a nice waiting room with donuts and refreshments while waiting to sign paperwork. In and out in less than 90 minutes. Our salesman Walen was top notch and a US Veteran. Special thanks to Isaac and Rocco for ensuring we had a great car buying experience. Thank you! Shawn Thomas

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 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 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.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

I just got my Tesla at Affinity. Milton was amazing. He knew exactly what I needed. I strongly suggest that you go see him before EV credit is over.

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...

I have been dealing with Mike Haggerty since 2016. ERNESTO has sold me 2 brand new cars. I truly love his customer service. Mr. Haggerty the owner came and greeted me. This dealership is amazing.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me

Great friendly staff very helpful best experience at a car dealership They did everything they could to help me into a vehicle

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Great experience with this dealership. I will come back again as well as refer my friends and family to this dealership. Sales guy Dan was a big help!

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

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.

I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.
