Used GMC Sierra 1500 Denali for sale near Willowbrook, IL

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.

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. :)

I was in the market for a used rubicon wrangler, Sherman dodge had the vehicle I wanted. Upon my arrival I was greeted by Jesse W and from the time I arrived to the time I left in my new vehicle he was very attentive to my every need! I felt like I left with an amazing deal!

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.

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside

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!

We just bought a high mileage TESLA from star motors. The entire experience and the car itself was great. Alex can actions as very reliable, open and ready to help always. Payment and shipping were managed in a very honest and trustworthy manner.

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 !

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.

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.

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 had a good experience with Chris Price awesome sales man.. no pushy sales tactics.. he was honest and straight to the point.. I have bad credit.. and was turned down from alot of different dealers Marino, Hawk,Naperville and Shermans.. all said No.. but Carmax have me thre car I wanted wth super low miles.. Thanx Chris you a good guy 🤗

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.

Amazing as always! Paul and his team always take care of me and the process is efficient.

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!

Went very smoothly The is the fifth vechicle we have purchased from this dealer and really appreciate the process of the purchase We plan taking this vechical back for service for the entire time we own it

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.

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

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...

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

I just bought my 2017 corvette grand sport two weeks ago. I flew in from New York. I can’t say enough good things about the process. We worked with Armin, he was top notch. He made every aspect about buying this car seamless and easy. He even arranged an Uber to pick me up from the airport to bring me right to the dealership. We just adore our new car. It’s perfect!! A million thanks 🙂 Joe and Denise

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.

A salesman named Ron Assaf helped me. I was looking for a used Car and I didn’t see the color I wanted so Ron asked me had I considered buying a new vehicle so he showed me a new Car and I walked out of that dealership with a new Car. Thanks Ron for all your help and service you gave me. You were Great.

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.

My wife and I went in looking for a used car, found new Mazda and fell in love with it. Great dealer and everyone is very nice. Highly recommend working with them.

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

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.

Fantastic selection of cars and a truly lovely team. The whole process was smooth and stress-free, with everything thoroughly explained from start to finish. They made buying a car such an easy and enjoyable experience. I would definitely recommend buying from them. Thanks

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.

I've been purchasing automobile from Haggerty in Villa Park for OVER 25 years. Also have them serviced at the Villa Park Haggerty location and body work done at the Glen Ellyn Chevy location. Good people and great service,

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.

Absolutely great people to do business with, From my first inquiry to the final purchase of my vehicle, the entire experience was handled with professionalism and genuine courtesy. I highly recommend them to anyone looking for a smooth and pleasant transaction.

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!

Loved working with Debbie! She was great and made sure I knew everything i needed to about the car and didn't let me worry about a thing!

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.
