Used GMC Sierra 1500 Denali for sale near Wheeling, IL

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.

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 !

⭐️⭐️⭐️⭐️⭐️ A 10/10 Experience at McGrath Honda of St. Charles! We couldn't be happier with our purchase of a 2025 Honda Pilot Elite AWD! The entire experience at McGrath Honda of St. Charles was absolutely painless and easy—exactly what you want when buying a new vehicle. A huge shout-out to our representatives, Gabe H. and Deanna B. They were not only incredibly friendly, but their customer service was truly exceptional. They were actively listening to our needs and what we were looking for, finding positive and productive solutions every step of the way. Their attention to detail was fantastic; they were very thorough in explaining the ins and outs of everything. From start to finish, this was a perfect experience. We wholeheartedly recommend Gabe, Deanna, and McGrath Honda of St. Charles. You won't find better service!

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.

My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable. I have to say that this was the best vehicle buying experience I have ever had. My next purchase will be with the Castle dealership in McHenry IL and I will ask for Tony to be my sales person.

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. :)

Mario did an awesome job with the customer service and did not feel pushy at all. Mario did everything he could to make a great deal that my wife and I could agree on. Mario and I connected so well that we decided to network after. Awesome customer service and awesome people. Thanks again!

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!

A1 car buying experience. The salesman Denzel was great. He was friendly and very knowledgeable. Thanks so much for such a great deal.

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!

Quick and easy! Recommending to everybody who need profesional service from beginning to end! Sasha

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.

Joe Aksamitowski does an incredible job in all aspects of customer service from beginning to end for me and my family. In this case I needed a new transmission, a costly and lengthy process, and was allowed to have a loaner car free of charge for 7-8 days in December 2025. Joe kept me updated throughout the process. Despite the cost of almost $7K after allowable deductions, I was very satisfied with the outcome. He is tremendous with customer service. I have spent well over $400,000 at this dealership over the past 30 years through the 3-4 dealership changes on 8-9 new cars as well as R & M. What is consistent is great customer service. In addition, Roger Aguilera and Chris Capperelli are also great with customer service. Thank you. Lowell B. Raven, CPA

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 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've been purchasing automobile from Haggerty in Villa Park for OVER 25 years. Also have them serviced at the Villa Park Haggerty location and body work done at the Glen Ellyn Chevy location. Good people and great service,

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

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!!

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.

Thanks again for all your help! Highly recommend! Excellent customer service Very accommodating and friendly staff If you’re looking for a used car this place is the best

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 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.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

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

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!

Bought a car for my daughter tim was great would definitely go back for my next purchase

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

Excellent service . Brandon was Great and very informative, friendly, professional and great to work with. I would recommend Martin Chevrolet Service for your vehicle 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.

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.

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.

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.

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.

We really appreciated how dedicated the staff at Huntley Ford were. We spoke on the phone and visited to check out a few vehicles with Daniel. He was very patient and wonderful to work with. Although we didn't purchase a car during our visit, we would recommend that anyone visits the dealer for a great experience.

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.
