Used GMC Sierra 1500 AT4 for sale near Valmeyer, IL

Conan Thomas was my service advisor and the service was excellent. Took care of everything and made this service call as easy for me as possible. I will always go back to Sapaugh.

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 love our new SUV! Kelly was great to work with! She is a straight shooter.

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 had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.

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

We worked with Chris Bittick (Chris gets 10 star's) to purchase our Blazer. He was awesome. Very professional, knowledgeable and friendly. He made the experience very enjoyable. Jim in finance was great to work with also. Want to give a shout out to Max too. Over all, great experience. It had the WOW factor.

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. :)

We had the best experience with Autocenters Nissan. Our salesman Nikolas Kennedy was amazing. He worked with us to get the best possible deal that worked for us. We love our new Nissan Frontier ❤️ We highly recommend Autocenters Nissan 😊 Robert Smith

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!

Kelly is awesome helped me trade my xxx for an amazing truck. Love it thanks

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.

I met with Dave Fisher, he made me feel very comfortable from the beginning all the way through the whole process of buying a used vehicle. No pressure, no stress. I was very happy I decided to go to Sapaugh GM Country. Thanks Dave for making the process and easy one

Great performance, hard to clean, everything, I expected. Getting lots of compliments and head turning. Stomping with thee BIG DAWGS!!!! Good gas mileage on highway.

Exceptional experience very good price Brian Ries is a excellent salesman had vehicle equipped exactly what were looking for

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

Shawn did a great job working with us to get us the terms we wanted.

Buying a used car from Carl Schaeffer at Nissan autocenter couldn't have been easier, a truly pleasureable experience. Definitely worth the drive to Herculaneum to see the car in person and test drive it. The car was exactly as advertised on cargurus!

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.

Great customer service, smooth and easy buying process, good help and detailed explanations. No pressure on the sale whatsoever. I gotta name drop here too, work with Corey Reno, the salesman’s is legitamitely honest, candid and very helpful/insightful. Would definitely buy from here again.

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 !

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!

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.

It was the best experience! So fast and easy! Ethan was great to work with! I will definitely be back to buy my next car!

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!

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.

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.
