New and used 2026 GMC Terrain SUVs for sale near Okawville, IL

Always an excellent experience. Everyone goes out of their way to get the service correct the first time.

I have had many Jeeps, when they stopped making the Cherokee I was at a loss until I came upon the GMC Terrain and so happy I did. Great style, performance handles great, many exceptional features, I spend a lot of time driving and never feel like it is tiring, lots of room in cabin and the cargo area. I have a new favorite, and it is the Terrain

The entire team at Monken has been helpful, friendly, caring, efficient, and caring. I brought my entire family (5 kids!) to buy a new van. Before we came, they worked with me over the phone to narrow things down. When I arrived, they took my messy van as a trade-in, took the car seats out and reinstalled them in the new van, entertained my kids with popcorn and candy (after asking our permission), cleaned up their spills and mess without making it an issue, made my purchasing process the quickest it has ever been, and I drove away with a new van, exactly what I wanted with a full tank of gas. I HATE buying cars. But since buying my last two at Monken, I'm a customer for life. I live over an hour away and will gladly drive the distance in order to have this kind of service that is UNHEARD of in the car-buying world. Thank you Monken!

I’m 56 and I’ve mostly owned trucks in my life. Out of the few cars that I’ve owned this 26 terrain elevation edition is the best car that I’ve owned. It’s comfortable and expensive gets good gas mileage plenty of room inside well designedand GMC has been a reliable brand for me over the years. I do recommend this car.

Friendly atmosphere, great service. I would 100% come back for all work I need done.

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

Very helpful staff. Absolutely no pressure to buy from Corey during the early phases of my shopping . Visited multiple dealers trying to find the right vehicle. When made decision on vehicle Corey and Steff did all the work. Online questions answered almost immediately. Even stayed late to accommodate my schedule. No hassle buying process. Made the 50 mile trip well worth it. Will definitely look here when in the market again.

Bruno was awesome and determined to get me the vehicle that I wanted. Which he did. he was selfless and made sure that everything was convenient for me. I highly recommend anyone seeking a new car to go to Bruno.

Our salesman Bruno was the best by far! We didn’t feel pressured to buy a vehicle, but at the same time we felt safe buying a car from him. He was very informative and made sure all our questions were answered. He called a week later to check on the car and let us know if we need any further assistance to reach out. I have recommended my family to go see Bruno at Cardinal Buick!

Total definition of teamwork love it very understanding and will work with you!!!!!! Love my car family

Go to Cardinal Buick/GMC! The staff is amazing and our salesman Bruno was amazing! Professional and understanding of what we came to buy! Love this place! Sent my brother in law to them and he bought a car too! I’m sure we’ll be back to buy our next vehicle too😊😊

This was my second vehicle purchase with Cardinal GMC, and I have to say, the experience this time around was a huge step up, all thanks to Matt Columbo. My first purchase didn?t go as smoothly, but I met Matt when I came back for service, and he immediately stood out. He took the time to notice an issue I was having and actually helped make it right, which left a lasting impression. So when it was time to buy again, I didn?t think twice, I went straight to Matt. He made the entire process easy and stress-free. He was knowledgeable, patient, and genuinely cared about getting me into the right vehicle. I love my new Buick Envision and couldn?t be happier with how everything turned out. If you?re heading to Cardinal, ask for Matt. He really goes the extra mile.
