Used GMC Sierra 1500 AT4 for sale near Hillside, IL

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark

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.

Great people to business with.Jeff and the owner very thoughtful and professional. Would refer anyone that needs a car or truck

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

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...

When people complaining about the car buying process this wasn?t one of them they were great!!!

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 !

Great vehicles! Great service! Highly recommend this dealership who’s looking for a hassle free buy and very transparent paper work! Thank you baha auto group!

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.

I always love coming here for service. Carlos and team are all very friendly and thorough. They have always taken great care of my car and me.

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!

We drove 3 and a half hours to go to this dealership. We could not have asked for anything more, these people are top-notch people. This place was clean, people were friendly and helpful. John O'Connell Was our salesman and we could not have picked a more perfect person to work with. We went in to buy a Yukon AT4, left with the Yukon, and purchased another car from them. We have found a car guy and dealership that will always have our business.

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

Excellent repair work, excellent service, excellent pricing. Things went so well in the service department with great experiences getting the service work done we decided to come back to Bill Kay Nissan and we had an exceptional time purchasing a new Rogue. Thank you, Bill Kay Nissan, in Downers Grove! You guys are the best. I will make sure all my friends and family know who to go see when they are looking for a car! Keep up the great work!

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. :)

Second car I purchased from castle gmc our sales person was Nubia /great experience every time helpful and always greats us as family highly recommend castle gmc Nubia and Brandon will take very good care of you . 👍🏻

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

Nothing much to say just talk to Sam.Very Profesional sales person highly recommend him, he didn't push me to run through hoops just showed results am greatful thank u Sam

Sam S. My sales rep. Was patient and honest. His no pressure approach was refreshing compare to the other dealerships I went to. They were quick and efficient. Repeat customer.

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.

Easy to schedule service. They shuttled me to my home and back and were super fast and on time!

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!

FANTASTIC CUSTOMER SERVICE!!! Highly recommend SchaumburgBob Bob Ott, provided timely assistance and understood the repairs that needed to be made. He explained step by step what needed to be done. Thank you for great service and a positive experience!

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.

Diamond Motorworks is truly a hidden gem! Rami and his team made the entire buying process an absolute pleasure! Their showroom is gorgeous and their selection of high end inventory is second to none! Thanks so much for making the first of many of my dreams come true 😊

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.

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!

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.

Always a great and personalized experience! Definitely a VIP experience with every transition and handoff throughout the entire experience. Dominic and the rest of the team personalize the experience, and go above and beyond. The follow-up is next level between the technology and personalized touch. They have a loyal customer in our family!

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?

Mike Lorenzo, Kevin O Boyle D Arct Luke Stiller were the best people I?ve ever dealt with in a car dealership and I bought over 20 cars
