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

These guys have old fashioned integrity. Great to work with and honest prices. Always a great selection of nice clean cars to choose from. Respectfully R. Pilz

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.

ABDUL was VERY helpful to us within moments of us walking through the doors at 9:00 a.m. Saturday morning. He facilitated our selection process from our initial inquiry to our final selection. He exhibited good salesmanship, active listening, leaning in, gaining rapport, relevant & meaningful story-telling, and carefully wove the common thread of love for family into the selling process...we even found common ground about cultural things that we found funny...The skills he exhibited and values we shared seem to be disappearing in this new economy. We LOVED Lewis. Lewis knows every aspect of financing inside and out. He's so smooth. He respects a "NO" then remains conversational and low-key until he gets to "YES". Smooth! Top Performer's Sales Training at its best! We connected immediately and beyond just an occasional LOL, we Laughed Out Loud - LOUD and OFTEN...By the time we left, we were tired, hungry, but IMMENSELY pleased with all of the contractual guarantees, servicing/warranty explanations, being financed by the company of our choice - and our friendship with Lewis. You'll LOVE his iconic signature!

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!

I bought a new 2023 F-150 XLT from Hopkins Ford today. Jaden was my salesman, and he knew every question I had right away. He was extremely helpful, and was an awesome salesman. I’m very happy to do business with him, and Hopkins Ford. We couldn’t find a price that was going to work for me, but we kept talking for 5 more days, and they kept working harder and harder to get the truck to me at the price I needed it. They were finally able to make it work, and I’m very grateful that they worked so hard for me. I will absolutely be buying more cars from them in the future. I would 100% recommend this dealer, and Jaden as your salesman. Thanks Jaden!

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

Salem worked hard for me I missed out on the truck so wanted to buy but they called everyday to try and help. I did not buy a truck from them but they helped anyway

Friendly staff, great price for the car. There was a far bit of waiting around but with the volume of cars they are shifting on a daily basis, it was kind of expected. From the very short test drive to driving out with my car was around 45 minutes.Would definitely use then again.

Elvir and Matt did a great job and I was pleased with the attention, negotiation and the car I got.

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

Brought my vehicle in back in January for some issues related to the oil pan. Victor and the crew at Hopkins took amazing care of me and empathized with me throughout the entire repair process. Truly appreciate these guys work ethic and customer first service approach. Need more dealer service providers like this across this country and this is the standard that others should strive to follow. Thank you again for the assistance with my F-150 you guys have earned my business moving forward for years to come.

Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

Thank you for getting my cehicle repairs done and workinf so hard to het me out of there to get to where I needed to go.

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 best experience I've had dealing with buying a car. Chris was honest and the best person to work with.

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 place to buy a vehicle. The staff is very friendly and the process was very easy

We are very happy with our Terrain Denali. Our first choice was the 2023 Lincoln Corsair 1a but there are no in inventory. The Terrain Denali was 1b. Great styling exterior and interior

I couldn’t be happier with my experience at Driven Auto of Dundee! I recently purchased a Tesla from them and the entire process was smooth, transparent, and actually enjoyable which is rare when buying a car. Eddie Baker was my salesperson, and he went above and beyond to make sure I got exactly what I wanted. He was knowledgeable about every feature on the Tesla, explained the financing options clearly, and made me feel confident in my purchase. The inventory here is top-notch especially if you’re looking for Teslas or other luxury vehicles. If you’re in the market for a vehicle, I highly recommend checking them out and asking for Eddie. He’ll take great care of you!

I love the Yukon. It needs a few censors changed out but it drives so smooth. Very glad we made the choice to purchase it

Offered more for my trade than the other dealership I was working with. Friendly staff, I will be coming back here for my next one

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.

Salesmen and all staff were helpful and worked with me on a great deal for the Gladiator.

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!

Everything about my experience was great. Organized, efficient, friendly. Karl was my car sales go to. He checked all the right boxes and now I have the perfect car, with the perfect rate, for my family and our adventures.

I didn't purchase the first truck I looked at, but did end up purchasing a different truck. My interactions with Brandon and others at Salem Autosports was pleasant and efficient. Highly recommend.

I live in the Indianapolis area and found the SUV my family was needing. I talked to Shawn and told him I wanted an honest description of the vehicle before I drove 5 hours to purchase it. When we got their it was exactly what he described. I would definitely buy from Shawn again!

On Nov 25, 2025 I met some AWESOME PROFESSIONAL salesman. I went to Kunes to help my Goddaughter buy her first car. I was approached with a warm greeting. Told Dylan Gentzen exactly what we were looking for. He listened to what WE were saying and not just eagerly trying to make a “sale” Not only did Dylan listen, he came thru for her!! KUDDOS! Thanks for giving my Goddaughter a chance when others didn’t. I typically DO NOT write reviews, but I have to applaud Kunes and Dylan. THANK YOU ALL! If you need, looking, curious about getting a car, stop at Kunes and ask for Dylan…

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.

Eduardo was fantastic at Huntley Ford! He was patient and knowledgeable while helping me choose my new Ford F-150. Highly recommend!

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Eduardo Del Rio helped me buy my ford explorer and made sure it was in my own liking

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

Buying my Camaro from Castle Chevrolet in McHenry was an outstanding experience from start to finish. I worked with Eric Loredo, who set the tone by doing a full virtual walk around and video of the car before I arrived, answering all my questions in real time. When my wife and I landed at ORD, the car was spotless and ready to go. Finance Manager Mike Lazzara had all documents sent ahead so I could DocuSign, making the delivery quick and smooth. Sales Manager Matt Knudson, GSM Jerry Spanier, and Andrew Sytsma (who wasn’t my salesman but still took time to chat and share product knowledge) all played a part in making this one of the easiest purchases I’ve ever had. The team knew my previous car was totaled in a tornado, and they went above and beyond to make this out-of-state transaction simple and stress-free. Eric and the entire Castle team reminded me that buying a car doesn’t have to be a battle. I would absolutely buy from them again.

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.

Martin Chevy in Crystal Lake is an AMAZING dealership with AMAZING people working there. From searching the right cars, making the purchase, financing and service, this place rocks it all!!! Highly recommended!!!

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Matt is sales was very open and honest. He worked to get the payment I needed!

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!
