Used GMC Sierra 1500 Denali for sale near Summit, IL

I recently purchased a car here, and Dan made the car-buying process quick and easy. He was honest, attentive, and helpful every step of the way. I bought a highly special used car, and Dan's knowledge and guidance made me feel confident throughout the process. I'm very happy with my new car and the service I received. I would definitely recommend Dan and this dealership to anyone in the market for a vehicle.

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!

They give you the best price without the hassle. Quick and easy. I’d Definitely recommend.

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

Easy no pressure buying experience. Service department is friendly and efficient. Salesman David, business manager and delivery consultant were all efficient. I recommend this dealership to anyone in the market for Land Rover or Jaguar vehicles.

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.

Everyone was super welcoming, and the hospitality was great. Kurt is an amazing person to work with, I?ll always recommend him for any business.

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.

Very professional, excellent communication Friendly staff, and had the vehicle we wanted, would deal with them again

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

I’ve always had very good service from Glendale Nissan. Fast, efficient and thorough. Pricing is fair. Always have good coupons that help!

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.

Awesome service from Jose!!! Very patient and kind. Explained every detail. All dealerships need a Jose!

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

My recent purchase from B & M is probably the best dealership experience I’ve ever had! Dominic and Chuck were friendly, extremely knowledgeable and helpful… B&M has a great selection of vehicles, a great service team, a wonderful sales team and the showroom has some CLASSIC cars that you can view as you wait! 10/10 recommendation!

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.

After extensive searching I found a truck at summit auto center that matched my needs. After deciding to buy the truck, the whole process was actually easier than some local deals I have made. The condition of the truck is outstanding! At 6 years old it is in a condition that one would expect of a 1 to 2 year old unit. I am very pleased with the deal. A search for any trucks I may need in the future will start at Summit Auto Center

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...

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 selection of cars. I bought my Tesla at Affinity and couldn't be happier. After going to a few different places Affinity had the cleanest and by far the best service. I will be back again when the time comes.

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.

I recently purchased a 2026 GMC 2500 Denali, and it has exceeded all my expectations. The truck is powerful, smooth, and built for both work and comfort. The luxury interior, advanced technology, and attention to detail make every drive enjoyable. Towing capacity and performance are top-notch—perfect for heavy-duty needs without sacrificing style. A huge thank you to Tony Gullette, who was an outstanding sales professional. Tony made the entire process easy and stress-free, providing clear answers, honest advice, and exceptional customer service. They went above and beyond to ensure I got the best deal and left completely satisfied. If you’re in the market for a premium truck, I highly recommend the GMC 2500 Denali and working with Tony. You won’t be disappointed!

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.

Mike Lorenzo, Kevin O Boyle D Arct Luke Stiller were the best people I?ve ever dealt with in a car dealership and I bought over 20 cars

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?

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.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

My sales advisor, Izhar, was extremely helpful. There was a great selection of vehicles in stock, and all the employees were very friendly and supportive. My sister is very happy with the car we purchased. Highly recommend.

I purchased my 2010 Sierra in 20111/2 35,000 miles,l now have 241,000 miles it’s not a work truck other than maintenance repairs it’s been a great truck. I have to say it still runs great,sounds good. I’d buy another one!

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Most pleasant waiting room anywhere and the friendliest service people.The mechanics always attempt to fix problems before they start. Also wait time ia always fair.

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 !

My sales consultant Travis was excellent he has great customer service and explained everything clearly. He made me feel very comfortable from his hand shake to his smile. He did a great job. Thanks Travis.

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.

Adulfo at Acura of Westmont delivered outstanding customer service from start to finish. He was professional, patient, and incredibly knowledgeable. Every one of our questions was answered clearly, and he took the time to walk us through all of the technology and features in our new 2026 Acura MDX S so we left fully confident using everything. His attention to detail and genuine care made the entire experience smooth and enjoyable. In addition, the entire staff at Acura of Westmont provided first-class service. This was truly the best dealership experience we’ve had, and I will only buy from Acura of Westmont in the future. I highly recommend working with Adulfo and the team at Acura of Westmont.

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!

Steve was a great salesman and helped me find the car I was looking for with everything I needed! Steve and his team were a big help and I’m looking forward to enjoying my new Tahoe. Thanks Advantage!

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!
