New and used 2026 GMC Terrain SUVs for sale near Wheeling, 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.

We traded in our 2019 Buick Encore for this Terrain. Let's just say WOW on the room and comfort. We travel back and forth from NC to Ohio as family lives in both States. Well the Encore was nice on gas but not comfortable on long trips at all. This has great leg room (heated seats (both back and bottom) and this is a game changer for me with my arthritis. The cameras in this car are awesome. You can see clearly what is behind you when backing up. The lane assist will give you a little buzz in the seat on the side you have drifted too or if you are getting too close to an object or person when backing up. Nice cargo area. The back seat can also handle 3 adults with enough leg room. It's very comfy back there, I road in the back on the test drive since I sometimes sit in the back on trips so I can n change positions more. The 15 inch info center is impressive for sure. Still learning how to use it. If you want comfort in a nice looking SUV this is the one for you.

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!

I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

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

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

Great staff and very good deals on new vehicles. Quick, friendly and very helpful. I would recommend if your looking for a great deal check with these guys first. They will get you that Great deal others can't.

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.

My sales person at Castle Chevrolet was Tony Twall. He was awesome to work with. He answered all my questions and was very knowledgeable. I have to say that this was the best vehicle buying experience I have ever had. My next purchase will be with the Castle dealership in McHenry IL and I will ask for Tony to be my sales person.

Great people to work with. Very professional, courteous, helpful and thorough. They follow through with all of their commitments. The trade process was straight forward and was just as agreed.

Expectations were set and met on a Saturday with college football on. Two separate seating areas in case you wanted the option to watch something else. There's also a kids' area if you have a little one who needs to be entertained for the time you're there.

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

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.

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.

We had an incredibly smooth and pleasant experience at this dealership from beginning to end. The entire process was seamless from start to finish. Every staff member we interacted with was helpful, courteous and professional. Buying a vehicle from Seann Omara was particularly wonderful— he is knowledgeable, helpful, and genuinely committed to making sure we got the best deal possible. We left very pleased and would happily recommend Napleton Buick GMC to others!

Brian at Marquardt service department was extremely helpful to get my car all ready for winter with a new set of tires. I appreciate having a great dealership near by to handle my car needs.

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

Wonderful customer service, amazing financial people, overall amazing experience! I’ll definitely be back again
