Used GMC Sierra 1500 trucks for sale near O'Fallon, IL

Outstanding service department. The facility is always clean and the service technicians and drivers are always courteous. I would recommend Jack Schmitt Chevrolet to anyone.

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

I always get great customer service from everyone at Laura Buick. My go to guy is David Day. They always do a great job with any issues with my car.

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 bought a new 2026 Colorado Trail Boss from Kevin Jones at Weber Chevrolet in Granite City IL. i felt I needed to write a review since I had such a pleasant experience. First time i can remember having a relaxed no high-pressure sales representative. Kevin was a straight shooter and was great to work with. I felt he dint try to talk down my trade in and was very professional. We came to what I felt like was a fair deal, and he went the extra mile. Set up all my phone and OnStar, brought me a water, helped me move all my stuff over to the new truck. I honestly felt like he wanted me to have a pleasant experience, and I did. This guy is 5 star

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.

Would never use anyone else, have bought many trucks and cars from them through the years. We also have them serviced there. Also they are awesome.

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!

Great store. Good and honest people. Prices were fair. Internet department was awesome! I didn't buy this time, but I'll be back.

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.

A very special Thank You to both Chad Sigsworth (Sales Associate) and Patrick Amann (Service Associate) who both assisted in the replacement of my engine. Both gentlemen were dedicated from the begining to the end of this replacement. They both stayed right on top of things and kept me well informed until the job was completed. I will always purchase any future vehicles through Dave Sinclair due to their honesty, dedication, and treatment of their customers. They have one of the best staff I ever had the pleasure of working with. Keep up the great work. Sandra Hearn

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

Taking a 12-year-old CTS Sport Wagon to a Cadilllac dealership for service tends to make one brace oneself for the onslaught of potential sales pitch that naturally occurs when an older model comes in for service and the dealership is in the business of selling brand new ones. To my pleasant surprise the approach was quite the opposite and Terry, along with members of the sales staff, all seemed genuinely happy to provide service work without the sales pitch. The work was completed quickly and the car remains the reliable and fun-to-drive car that has been a testament to the make's time-honored claim as "Standard of the World". Even when I mentioned that a new Cadillac might be in the cards someday, the staff was happy to know they were helping keep one of the most iconic models that Cadillac has produced in recent years on the road. Thank you, Terry and the staff who worked diligently to get my car repaired and back to me well within the time frame that had been promised.

I bout this truck new in 2008 and traded it in in 2020. This truck gave me 12 years of reliable transportation. I used this truck for everything from commuting to work to camping with the Boy Scouts.
