Used GMC Sierra 1500 Denali for sale near Bartlett, IL

Anthony greeted me in the parking lot and was friendly and professional. He quickly brought the car out that I wanted to see. Negotiations were very fair and the paperwork was done in a timely maner. I love my new/pre-owned HyundaiTucson. Thank you Anthony and the team! I'll see you again when I need my next vehicle.

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.

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.

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 !

We bought a '23 Tahoe Z71 and the sales process couldn't have been more seamless. Our salesman, Paul Degrazia, was terrific and made the purchase an enjoyable process, which is pretty rare. We came to terms quickly and we were finished within a couple hours. We love the vehicle and definitely recommend Bill Kay and Paul.

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 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.

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. :)

Every Time I visit advantage chevrolet I receive great service. I have chevy dealership near my house. But I like going to this one. This is where I bought my car.

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.

Had an amazing experience here at Sherman dodge with Jesse W, he listened to our wants and needs and made sure we got a great deal! Definitely going to send my friends and family here as well.

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.

Thank you to the service team for your getting me all set for my roadtrip!

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!

Sam worked with me, I’m north of Detroit, Michigan and had a lot of questions! He went out of his way to take videos and pictures of the vehicle I was interested in. He spent 2 weeks answering all of my questions and being very professional and patient with me! When I finally got there and took it for a test drive I was amazed at how clean the vehicle was and how quickly we were taken care of - it was a seamless process and everyone was very friendly and accommodating! Thank You!

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Service is great and friendly and they will do everything they can to make sure you get your car in and out no problem. They’re awesome! -jimmy sands

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.

From the sales assistant through to the purchasing team, everyone we dealt with was excellent. The staff demonstrated a strong knowledge of the vehicles and took the time to explain everything clearly and thoroughly, ensuring we fully understood all of our options before making any decisions. Nothing felt rushed, and every question we had was answered patiently and professionally. The entire experience was made easy and stress-free thanks to their friendly, approachable, and genuinely helpful manner throughout the whole process. We felt well supported from start to finish and would not hesitate to recommend them.

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

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

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.

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.

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...

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.

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 Cars and also good service. Vincent Vega was very helpful thank you Vincent for all your help. This is our third car from Castle Buick GMC. We loved thank you .!

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.

Brought my car in for service and some new tires. Jen was able to help me and gave me a car to take to pick up my son while they were working on it. Love the service staff here!!!

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

Great service. The service department was courteous and friendly. My car was serviced and ready to go in a reasonable amount of time. I was very satisfied.

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.

Great people to work with. Very professional, courteous, helpful and thorough. They follow through with all of their commitments. The trade process was straight forward and was just as agreed.

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

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.

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.

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?
