Used GMC Sierra 1500 Denali for sale near Gurnee, IL

excellent costumer service. Chris is very helpful and accommodating. Friendly staff. on time service as promised. I highly recommend this dealer to all. Beautiful car displays.

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

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.

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.

Best dealer ever. Tatiana did a great job..She is very smart respectful and she has a lot of knowledge. My next car l m going to buy with them also and with Tatiana of course. If you are looking for a good price and a solid car go there and ask about Tatiana. Mike volvo v v90 cross country

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

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.

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.

We were looking at options for a family car, and Sam was incredibly helpful He took the time to explain everything in detail and walked us through the different options available. The service we received was excellent thank you, Sam.

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

Marquartd of Barrington is an amazing dealership because of their integrity and great customer service! I bought my new car 2017 and have relied only on them to maintain it. They are trustworthy and truly care about the customer. Their work ethic and philosophy reflect heavenly standards. I will never go anywhere else!

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!

They really made this a smooth experience. Especially when it came to the actual purchase of the vehicle. We dealt with Nick as our sales person and he was great at communicating with us and insuring any needs or concerns were addressed.

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Nathan and Kevin was great. They made the car buying experience very simple and made sure that all of my questions were answered. Im very happy with my new Envista.

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.

Went for a scheduled oil change. Waited about 1 hour, which is pretty normal. Was treated with respectful & courteous service from the service adviser. Have been going to this dealership for a long time. I would recommend them for your service needs.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Great service and people fast and easy buying process will recommend to other family and friends fun environment and provide coffee and water will be back for all my service needs and repairs

They are so busy it sometimes takes a while to get an appt; but service techs provide good service. Dennis Narsson has ben my tech advisor for my last two visits; has explained the problems and kept me updated as to progress. I have been a service customer for ~8 years.

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.

Ted was great it was a great experience this is my fifth car I bought from this place

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 service this is my 3rd purchase. Growing up as a teenager a G37 then a c43 and a s5. Superb you are the best everyone. Usman and Hamza !

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!!
