Used GMC Sierra 1500 Denali for sale near Wheaton, IL

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

I had avery good experience shopping for a new vehicle, Richard Matway my salesman was very knowledgeable and helpful.

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.

Victor Riley was so professional friendly. Knew everything about the vehicle I bought walk me through everything. Got my phone hooked up to the vehicle and when it came for financing the team was just great. Thank you to team advantage

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!

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.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

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.

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.

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.

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.

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. :)

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

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 !

Great experience in the service department. Efficient and personable! Communication was on point from start to finish.

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 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!

Excellent sales people! A truly great experience with extremely knowledgeable people. The auto was in magnificent condition, and the sales procedures were very well executed. It is a dealership that I will continue to purchase from and 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!

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.

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.

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.

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.

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.

If you’re not looking to be served champagne and want a simplified buying experience this is the place to go! The no haggle pricing takes some of the anxiety out of the car buying experience, and if you cross check the vehicle on cars.com it will directly tell you if you’re getting a good deal or great deal or fair deal. We purchased a Porsche Cayenne from them and Dan and Brian were awesome! Thank you!!

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.

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.

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.

Very good selection of cars and a highly professional staff. The whole system was very well organized, which made the experience smooth and stress-free. I’m very happy with the service and would definitely recommend to others.

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
