Used 2023 GMC Sierra 1500 trucks for sale near Countryside, IL

They are absolutely great. They always take care of my vehicle & make me feel like a valued customer. I always recommend or refer others to Jennings Chevrolet.

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.

The process was easy. Went to see the car but they were waiting for a part. We liked it right away. When it was finished they called us to test drive. Dan and Dave were terrific no pressure. They gave us a figure and we gave them ours and they did more than we asked for including accessories. John in finance and John the gm were also terrific. I rate this dealership very high.

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Bought a 2025 Sonata today. Dion was great to work with and the buying process was the quickest I've ever experienced when purchasing a vehicle.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

I initially checked to see if the SUV I found on cars.com was still available to look at. After sending the email, via cars.com, I got a text back within a few minutes saying the SUV was available and a salesperson would check with me to set up an appointment. I spoke with Jamie shortly thereafter and met with her at the dealership. The SUV was washed and ready for me to see and test drive. The rest of the purchase experience was fantastic!! For me, number one of the top three car buying experiences ever. I’m now retired and have bought a lot of cars. No high pressure, just great customer service. Keep up the great work Jamie and Bettenhausen!

I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀

Salesman was very professional, courteous, and very helpful. Transaction went smoothly and to my liking

Andrew Allen was amazing partner in my purchase so patient and great knowledge related to my Encore and Buick. The walk through was very thorough even providing me with his direct access for all future questions.
