Used GMC Sierra 1500 AT4 for sale near Mount Prospect, IL

Robert was amazing, understanding, helpful. And patient , he took the time out to help my sister find her dream suv . I definitely recommend

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Good service, friendly, clean, explained all features cars has. Very patience. would definitely recommend to anyone looking for a car. Wasn't there all day just a couple of hours.

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 !

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

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!

Very simple. Every aspect of my purchase was simple and straightforward. Bruno my salesman and Kevin the Manager went above and beyond from the moment I walked in. Well done.

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.

Excellent service Professional service Quick service Polite customer service Excellent customer communication Very detailed repairs

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 am beyond pleased and impressed with this dealership. Working with Rami and his team was easy, efficient, and professional. I used my own credit union for my financing and even they said what a pleasure it was working with Rami and Diamond and just how thorough and on top of things they were. I had never shipped a car out of state before and this was also my first Porsche and I’m sure I wasn’t the easiest to deal with at times, not on purpose of course, but just because it was such a new experience. I felt very taken care of and accommodated with everything I needed. Great communication and very fair. I can’t say enough good things! Very very happy and this dealer is top notch with quality of cars also - immaculate cars and care of them. My transport company even commented how nice this dealership is. We will be back for sure ! Thank you!!!

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.

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.

Wide selection and no haggle are a plus over other dealerships. I like being able to see how many different makes and models. CarMax is the only place I will shop

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

Bought 3 work trucks. Good price, no nonsense or upsell. 2 months have gone by and I am very happy so far. The amount of trucks they have is beyond belief.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Excellent service. I have no complaints. I always bring my car in for yearly service.

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

It was my first time at this dealership and will return for future repairs.The service representative kept me informed which made the process smooth and quick, with clear explanation.

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.

Carlos es muy amable y nos atienden todas esas necesidades para nuestro camioneta. Gracias por todo Carlos

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.

Great staff and very good deals on new vehicles. Quick, friendly and very helpful. I would recommend if your looking for a great deal check with these guys first. They will get you that Great deal others can't.

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 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.

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!

I purchase a 2019 Qx60 my experience was very very good sale person Thomas pates did a wonderful job to get me in this car everyone was helpful I will purchase another vehicle from there I am from Milwaukee thanks carwise

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!

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 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.

See the salesman, Mike super nice guy. He will take your time with you and not push you like most. Do super down to earth person. I would go back there again. actually, everybody there is super nice. They will take care of you.

All the financial numbers where accurate and the staff was honest at the end of signing the paperwork When I came next day to sign the paperwork I was surprised that finance staff had even better interest rate than day before that we verbally agreed

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!

Bought a 2022 Bronco Sport. Just love it. Joe delivered it today. He stayed and helped me setup the FordPass. Thanks Joe L. & George in finance.

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.

Matt was very friendly and provided me with all necessary car information. Well done today

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.
