New and used 2026 GMC Terrain for sale near Deer Park, IL

I had a great experience purchasing my truck with Jamie Liszka as my sales consultant. Jamie was not pushy at all and truly allowed me to make my decision on my own terms. They were very transparent with all the information provided and took the time to address and respect my concerns throughout the process. The entire experience was quick, easy, and stress-free, which made buying a truck much more enjoyable than expected. I would absolutely recommend Jamie to anyone looking to purchase a vehicle, and I would definitely go back again for a future car purchase.

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

Staff was amazing and got me what I wanted. I told them a price I wanted to spend and they did not try to sell me anything more.

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.

This was my first time buying a car at a dealership and I feel really grateful that Jamie was my salesman the day I went to purchase my car. He matched my energy and determination to get the car that I had my eye on. Not once did I feel pressured about anything and he made me feel so comfortable to ask any questions about the whole process. It was a very quick process running numbers and everything and I really do thank Jamie for that because he got straight to the point and I loved his transparency. 10/10 would absolutely recommend working with him.

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.

Chris Lahey was an exceptional person to deal with and got us the car of our dreams!

I recently purchased a 2026 GMC 2500 Denali, and it has exceeded all my expectations. The truck is powerful, smooth, and built for both work and comfort. The luxury interior, advanced technology, and attention to detail make every drive enjoyable. Towing capacity and performance are top-notch—perfect for heavy-duty needs without sacrificing style. A huge thank you to Tony Gullette, who was an outstanding sales professional.
