Used GMC cars for sale near Union, IL under $899,990

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Amazing experience. Made the process so simple for me to get what I want. Would definitely recommend to everyone

Marquartd of Barrington is an amazing dealership because of their integrity and great customer service! I bought my new car 2017 and have relied only on them to maintain it. They are trustworthy and truly care about the customer. Their work ethic and philosophy reflect heavenly standards. I will never go anywhere else!

So far I have been enjoying my 2025 GMC Canyon Denali. It has a great ride and is very comfortable. The Canyon drives very nicely and has plenty of power for my usage (I don't tow anything). It tracks well and has a very smooth ride that rivals previous BMWs (328 and X5's). I have had zero issues but the vehicle is only 1.5 months old (approx 1,700 miles on it). THe only downside (which many people agree on) is that it is seriously lacking storage space. Center console storage is about 1/2 what it was in my 2020 Jeep Wrangler and under seat storage (rear seats) is almost useless ..very little space. That being said, I'd still recommend the GMC Canyon and hope it continues to impress me.

Great people. Great service. Highly recommend Erick and team. They will give you a solid deal

GMC Canyon Denali with the 2.7 Duramax diesel is a loaded power house with great fuel economy. 4x4 has a towing capacity of 7000 pounds, the best in class. 31 MPG on the highway! Previously owned a Tacoma but it would not pull our travel trailer with the V-6. Highly recommend the Canyon diesel, if you can find one!

Very smooth experience. Seann is an excellent young salesman. Darien will do anything to work with you. Erick, the manager is very accommodating. A++++ dealership.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

Jon David is an asset to your company he’s a gentleman and a scholar. He put a deal that I won’t forget, and I won’t forget him. My son was very happy and he treated him with courtesy.

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

Thank you to the service team for your getting me all set for my roadtrip!

As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family

Fernando Rodriguez was an amazing help in our search for a used car for my son. His follow up was great and went out of his way to get answers for all of our questions and concerns!! Thanks again Fernando!!!

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

A very stress free experience. All good. Service writer pleasant. Very easy dropping off and picking up. I?ve always been happy at this dealer and service dept.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Got it for the ride ,comfort,great gas mileage on trips,can do a 750 mile trip and not be warn out from the ride.Can carry a lot of stuff .All the different options are great

Great site with an excellent selection of cars. The entire process was smooth and hassle-free, and I was able to buy with complete confidence. I highly recommend this site to anyone looking for a quality vehicle.

Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

The dealership responded quickly via email. Did not end up looking at the vehicle. Appreciate the quick response.

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

Since moving out to the NW area we have been going to Bigger Chevrolet for service. We only had an issue one time and it was handled immediately by the owner. For me that says a lot so I?ll be a constant customer. When ready to upgrade my vehicle this is where I?ll go because if you have a good service department and the owner responds to any issues, no matter how small then it?s an honest dealership worthy of my patronage. Thank you.

traded in my 2013 buick enclave for this 2023 gmc acadia. i think the ride is a little better , fuel mileage is better over all comfort is great. Ed at Patriot Buick GMC was great in explaining all its features.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Our sales person, Joel Storm, was friendly, informative, energetic, and interested in what I needed in a car. He helped me pick out the right vehicle for my needs.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Although I didn't buy a high end exotic, I was treated like I was buying one. The 2007 XKR was wonderful and Jackson went above and beyond to answer all my questions, inquiries and upfront about everything with respect to the car. It was prepared beautifully and the transaction was as smooth as could be for an out of state buyer. I would recommend them to anyone looking for a specialty vehicle and hope to deal with them again in the future.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Michael Stefanik is the opposite of the traditional car salesman we love to hate! He's a down-to-earth guy doing a great job.

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.

Communicated with John Leno from the Schaumburg facility online. John understood my needs and responded quickly with Jeeps to review - after a bit of humming and hawing on my part, I changed my mind to trucks. I found a truck at another facility, John had it tranferred and within 2 days my soon to be truck arrived - and it is a beauty. John was training Matt and they both demonstrated immense knowledge throughout the interaction and I appreciated the ease of communication (not pushy). I cannot comment on the financing portion of the transaction, but closing went just as smoothly with Hubert and his supervisor. WHile impressed with my transaction I was also impressed with the amount of time that was placed on the training of new employees, or employees transferring. While yes my truck need a repair on the fog lights, it is covered under their warranty, I am highly impressed with my experience. From walking in the front door, to having John take my picture of me and my truck with a giant yellow ribbon... every individual at Carmax truly made the buying and trading experience a wonderful experience. Team Schaumburg, keep up the great work, each of you understand the true meaning of Customer Service, and that is important to some customers like me who still cherish old school values.

Jonathan and Kahn were amazing. As always at Lake City GMC no pressure, very relaxed buying experience. Love my Acadia so much that this is my 4 th one.
