Used GMC Sierra 1500 Denali for sale near Wheeling, IL

Kevin was outstanding kept me abreast of the servicing of my vehicle. Would recommend the dealership to everyone.

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.

Eduardo gave me an amazing service at the dealership and helped me find a car.

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. :)

pretty good service. always courteous and consistent.

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!

Matt, Azbel were top with great first impression, and even better lasting impression! Great Service also from Moshe, Jeremy, Tino, Tamu, and welcoming crew. I am happy with my beautiful and spotless new car and dealership is the same. Friendly and very knowledgeable crew! I send everyone there for a great car, caring and trustworthy staff who will help you select the vehicle that's right for you!

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.

Great dealership , Great dealership, great dealership, great dealership, great dealership, great dealership, great dealership, great dealership, great dealership, great dealership, great dealership, great dealership, great

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!

Nothing much to say just talk to Sam.Very Profesional sales person highly recommend him, he didn't push me to run through hoops just showed results am greatful thank u Sam

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.

amber was very helpful. she made buy a car very easy. go see her for your new chevy

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.

Happy to purchase from this dealership rather than others in town! Turned out to be much better deal and car. 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 !

From originally purchasing my car at Haggerty to having my car serviced at Haggerty, my experiences have all been positive. Everyone is friendly and answers all of my questions. Work is done well and on time.

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.

Great experience! Minimal hassle with price. The salesman was awesome! The vehicle I bought was in an excellent condition.

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

Bought my first car here! Great deal! Nice people! 5 Stars service! They make me feel like 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

We had an excellent experience from start to finish. The entire process was smooth, professional, and very welcoming. A special mention to Ramy, who truly made a difference in our experience. Ramy went above and beyond to ensure everything was clearly explained, and was incredibly helpful, patient, and friendly throughout. It’s rare to come across someone so dedicated to providing great customer service. Thanks to Ramy’s support and professionalism, the whole experience felt easy and enjoyable. I would highly recommend this place to anyone looking for quality service and a team that genuinely cares about their customers.

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 provided excellent customer service from start to finish. The staff listened carefully to what I was looking for and showed me several great options. They were honest, patient, and never made me feel pressured. The car was in excellent shape and priced fairly. The paperwork was handled efficiently, making the entire experience stress-free. I highly recommend Autos of Chicago to anyone.

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.

Easy to schedule service. They shuttled me to my home and back and were super fast and on time!

This is the second car I've bought from CarMax (I also once sold a car). Every experience has been fantastic but this actually ranks as the best. Sales Consultant LaShinda John answered every question I had via email and then, for financing, by phone so that I walked in with the exact make, model and trim I wanted waiting for me to test drive and pre-approved for financing. The entire in-dealer experience took less than an hour and a half. Fantastic company and fantastic sales consultant.

It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility. Overall very comfortable ride and smooth drive

Lots of Trucks to choose from. Very large compared to any other van dealer I have ever seen. The trucks all seemed to be in in pretty good shape. I ended up buying a cheaper truck for my business and it has been trouble free so far. Will check what the have when I need another van.

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.

Purchased a 2014 Cadillac ATS from Ryan. I got a grate deal and would recommend them to everyone.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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 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!

Second car I purchased from castle gmc our sales person was Nubia /great experience every time helpful and always greats us as family highly recommend castle gmc Nubia and Brandon will take very good care of you . 👍🏻
