Used 2023 GMC Sierra 1500 trucks for sale near Saint Charles, IL

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

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!

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.

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside

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.

Have trusted this dealership for over 25 years. I wouldn’t think of bringing my 2 Buicks anywhere else. They only do necessary repairs which I appreciate and will give you a timeline as to what to expect down the road when it comes to doing work. They value you as a customer and do everything they can to help you in all aspects serving you.

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. ??????????????????????????????????????????? ?????????????
