New and used 2026 GMC Terrain for sale near Oak Brook, IL

Big thanks to our salesman Brian for excellent service. Very through and he,Paul in finding the right vehicle for us. Prompt courteous service. A very satisfied customer. Highly recommend Woody and ask for Brian.

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

This dealership was great the hospitality was through the roof, though we didn't make a deal I would 100% comeback.

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.

The sales staff is incredibly helpful but there’s one guy who stood out to me he was tall had curly hair & a beard. I don’t remember his name but I heard someone calling him Izzy. He was very respectful and you could tell he has a strong work ethic, that guy definitely deserves a promotion. I always see him working so hard at the dealership.

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.

Jackie was great! She was helpful and knowledgable. She seemed interested in helping me find exactly what I was looking for. I would highly recommend her.

Tony was our salesman and he took care of everything. Great experience thanks again and hopefully we get to see you guys again soon. The finance guy was great as well.

Elliott was incredibly helpful. He had patience and don’t oversell. This allowed us to find the truck that we wanted vs feeling like we were pushed to make a decision. Would buy from Elliott again.

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside

We walked in looking for a new or lightly used Cadillac. Coach Novak approached us and was absolutely fantastic. He was right he isnt a typical salesperson. He wasnt the typical slick talking, fastmoving stereotypical sales guy. He was respectful of my wife and my time and our needs. We got an great deal on a beautiful Cadillac. Thanks Rizza and Coach for all your service and attention in our new purchase.

I was impressed with the professionalism of Pola he is a great salesman .. keep up the good work

Great bunch of people . Not high pressure sales . They go above on trying to help you and accommodate . I wish I would have went with them but purchased another vehicle thinking payments would be lower but they turned out the same .

Always a great and personalized experience! Definitely a VIP experience with every transition and handoff throughout the entire experience. Dominic and the rest of the team personalize the experience, and go above and beyond. The follow-up is next level between the technology and personalized touch. They have a loyal customer in our family!

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.

As always, service and service reps were great-wonderful dealership and service department?have purchased cars from dealer for many, many years and will continue to do so.

My salesman Esad was great. He was very knowledgeable. Everyone was very friendly and helpful.

Amazing as always! Paul and his team always take care of me and the process is efficient.

The conversations I had with the salesman where Outstanding. In fact, he worked with me on my day off. It was a smooth process throughout. From the negotiation of price, financing to the end result delivery from IL to MO. Kudos to Steve Foley!!

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. Tony made the entire process easy and stress-free, providing clear answers, honest advice, and exceptional customer service. They went above and beyond to ensure I got the best deal and left completely satisfied. If you’re in the market for a premium truck, I highly recommend the GMC 2500 Denali and working with Tony. You won’t be disappointed!
