Used GMC Sierra 1500 Denali for sale near Warrenville, IL

Had to express my satisfaction with Eddie C with his professionalism, courtesy, and doing exactly what he said he would do. I reside in Arizona and have previously leased vehicles with M;Lady Nissan-without hassle and had a pleasurable experience. I would never lease another car from anyone else but Eddie C-

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 brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

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 worked with Rocky and had an amazing experience. This was my first car purchase from a dealership of any sort so I was very nervous, but he was incredibly kind and helpful and explained everything I had questions on. He was very thorough and I felt super satisfied when I walked off the lot with my car. Cannot thank him enough! Same with Matt the financial adviser there, he was also incredibly thorough and kind and explained anything I had questions on! I highly recommend this dealership and these guys! They were amazing! :D

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.

We had Cedric as our salesman, he was quick, knowledgable and friendly. Would use again.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

They were nice enough and willing to deal some. They told me that they were going to mail me some touch up paint but I have not seen it?? They did have the windshield replaced like the said they would.

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 love going to the Autobarn Volkswagen of Countryside! I have purchased 2 cars from Adrian, but the entire team is so fantastic to work with. The service department is very kind and thoughtful, as well as prompt. They will also give you a ride anywhere that you need to go if you are waiting for an extended period of time. If you are looking to purchase a car or just want a great place to get your car serviced, I would highly recommend Autobarn Volkswagen of Countryside!

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

Absolutely fantastic service from Kelvin. I would highly recommend this place to anyone looking to buy a car.

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!

Great experience with Luis Portales in sales. Showed us many different cars and options. No pressure to buy. Very easy to talk to and he listened to what we were looking for

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!

Service was good and quick no problems explained everything bought car there and service it there

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 worked with Billy. He were great to work with. Everything went very smooth and was a great experience. I would buy another car from them again! Everyone at the dealership we talked to was great!

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.

Barry at Icars of Chicago has been phenomenal since day one, and he truly shines even a year after I bought my car. When I reached out with a follow-up issue, he didn’t hesitate—he jumped in, listened carefully, and helped me get things sorted quickly. It’s rare to find a dealer that stays engaged long after the sale, and Barry embodies that in every interaction. What stands out most is how they stand behind what they sell. I felt supported and respected from the moment I walked in, and that commitment hasn’t faded over time. The team’s customer service is second to none—honest, responsive, and genuinely invested in making sure you’re happy with your purchase. Their focus on building long-term relationships, not just closing a deal, is the best I’ve seen anywhere. If you’re shopping for a car and want a dealership that treats you like family while delivering real value and ongoing support, I’d absolutely recommend Icars of Chicago and Barry in particular. Their customer retention is unmatched, and that peace of mind is priceless.

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Had an alignment performed while I waited, not sure exactly how long it took but I was done before I looked at my watch!! Thank you,

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

Matt is sales was very open and honest. He worked to get the payment I needed!

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!

Still shopping and may yet purchase from this dealer. They are an impressively large dealership. Yet, I felt welcomed and comfortable there.

Smooth ride strong motor decent gas mileage inside cab is loaded and very tastefully done along w easy access to knobs. Plenty of room. In back seat ! Aclassy looking Truck with a tacky looking owner!!

Juan was excellent to work with, we quickly agreed on a price, the vehicle was cleaned and ready to go by the time the paperwork was complete. Highly recommend.

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

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.

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.

Five-Star Experience at Castle Chevy Our experience at Castle Chevy was truly outstanding from start to finish. After receiving an invitation in the mail, we were contacted by Linda, who was not only friendly but also incredibly helpful. She took the time to understand our situation and helped us consider whether buying a car after bankruptcy was the right step. Her guidance was thoughtful and never pushy. When we visited the dealership, Kevin took over and exceeded our expectations. I had some hesitation due to our financial past, but Kevin was patient, professional, and informative. He clearly explained how purchasing a vehicle could help us begin rebuilding our credit and finally get out of a costly car rental situation. What impressed us most was Kevin?s genuine commitment to our needs. He didn?t try to steer us toward just any vehicle?he helped us find the right one for us. He also worked hard to secure the best possible financing available. The entire process, including the paperwork, was smooth and stress-free thanks to his outstanding support team. Although I don?t remember every staff member?s name, I won?t forget how respectfully and kindly we were treated throughout. At Castle Chevy, we never felt like just another number. The team made us feel valued and respected. That?s why I?m giving them a well-deserved 5-star rating.

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.

Worked with Brian again and had a smooth and great experience. I highly recommend this dealership and Brian.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Great site with an excellent selection of cars. The entire process was smooth and hassle-free, and I was able to buy with complete confidence. I highly recommend this site to anyone looking for a quality vehicle.

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.

It was professional and satisfying. Staff was friendly and accommodating to my schedule. They kept me updated to frequent updates on status, explained all features of the car.

I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.
