Used GMC Sierra 1500 SLT for sale near Bartlett, IL

My service advisor, Michael, did a great job of communicating the progress of my service appointment. Not all the necessary parts were in stock after the diagnosis, but he kept me apprised of the status of their arrival and made sure I had a loaner when they came in. The technicians did a great job and returned my vehicle in great condition.

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?

This dealership was great the hospitality was through the roof, though we didn't make a deal I would 100% comeback.

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.

We had an incredibly smooth and pleasant experience at this dealership from beginning to end. The entire process was seamless from start to finish. Every staff member we interacted with was helpful, courteous and professional. Buying a vehicle from Seann Omara was particularly wonderful— he is knowledgeable, helpful, and genuinely committed to making sure we got the best deal possible. We left very pleased and would happily recommend Napleton Buick GMC to others!

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

Overall I had a pleasant experience with this dealership and would definitely return when I purchase my next vehicle.

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.

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.

Matt in sales is extremely professional. His knowledge of the vehicle was obvious. He throughly explained the car's features with me. I'm glad he was my sales representative with the Castle Subaru dealership.

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 !

Karl here at rides unlimited was beyond helpful on our buying experience. He was able to somehow Get us down to the price range we wanted and worked on the overall price the whole time. Even when we thought we had what we thought was the best deal he continued to work and somehow found us something even better. The selection here has something for every price range and the staff goes above and beyond.

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 would like to thank Tommy for making the purchase of my 1977 Caprice Classic Landau which I have named “Tammy” an easy transaction . I was very nervous at first buying a sight unseen vehicle but the video and pictures from Tommy were spot on! It took me more than 2 years to find this rare vehicle . If you are on the hunt for a special vehicle I feel you can’t go wrong workin with London Motors. Give them a shot for your special ride

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 had a great experience with them! They made the process very easy and even gave me a better rate than my own credit union, which I've been with for over five years. I highly recommend them to anyone looking for excellent service and competitive rates. Thank you!

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

went it to look at a car that i saw online, called to check if it was available, the moment i stepped in they made me feel like i was family and took really good care of me. Great customer service, and very friendly

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.

Great Prices, staff and selection of vehicles to choose from! Thanks Jose for an amazing experience

We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

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 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!

2017 gmc sierra 1500 bought this truck from them and I’m very happy with the condition

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.

Great experience from beginning to end. No pressure at all, very professional staff, and smooth process. I would definitely buy there again.

I really like my nw, to me, 2015 GMC Sierra Denali. The salesman, Terrance Lin was very efficient, helpful and courteous. Thank you very much.

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

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.

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

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...

The moment I walked through the door, I knew this was the dealership for me. First things first, no pressure! I was braced to be swarmed as soon as I walked. But no, just a wide selection of vehicles, chill sales people and most importantly no pressure to buy. I told them the car I wanted to test drive. They copied my license, gave me the keys and plates and sent me on my way. The car was perfect with a few items to be addressed. They resolved all issues without any pushback. Gave me a fair price on my trade in, and sold me a wonderful car. I am happy! I highly recommend Rides Unlimited! Thank you Steven Partida and Karl Wilfinger for your assistance.

Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

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.

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.

Eva and the team at Castle cars of Naperville we great! In and out, the team was friendly and very attentive to my questions and needs. Highly recommend!

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Great experience overall. I was offered a fair deal without any pressure or unnecessary upselling. Chuck Fioravanti was straightforward, answered all my questions clearly, and made the whole process easy and stress-free. I?d definitely recommend this dealership to anyone looking for an honest and smooth car-buying experience.
