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

I and my wife only use the dealer's services for maintenence and repairs. We are always satisfied with the quality of the repairs and the friendliness of the office technicians

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.

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.

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.

I brought my car in for an oil change and multi point inspection. the inspection dealed that I a front brake issue. Mike, the employee I dealt with describe the issue and what it would take to repair it and how long I would have to wait he offered free transportation home if I wanted. because of the distance that I would have to travel there and back to home, I opted to delight the two hours in the lounge. I had coffee and water and I was fine. Mike came in several times to talk about the repair. He also said he had a rebate coupon I could use and he pointed out. I had points in my Buick awards account that I could convert to dollars to pay for the repair. That was very good service save me money and the car is running fine

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

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.

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.

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!

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.

We bought a '23 Tahoe Z71 and the sales process couldn't have been more seamless. Our salesman, Paul Degrazia, was terrific and made the purchase an enjoyable process, which is pretty rare. We came to terms quickly and we were finished within a couple hours. We love the vehicle and definitely recommend Bill Kay and Paul.

Had the pleasure of meeting and working with Jamie. Best salesman we have worked with!

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.

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.

My first experience at this dealership will definitely bring me back. We are so happy with our purchased! We had Alex Alverio from Sales, he was very professional & helpful, has awesome customer service & we highly recommend Alex. Thank you so much and keep it up!

Anthony greeted me in the parking lot and was friendly and professional. He quickly brought the car out that I wanted to see. Negotiations were very fair and the paperwork was done in a timely maner. I love my new/pre-owned HyundaiTucson. Thank you Anthony and the team! I'll see you again when I need my next vehicle.

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.

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

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 experience with Sunset Auto was outstanding. They have a great selection of used cars, all in excellent condition. The sales team was friendly, honest, and very helpful without being pushy. They worked with me to find a car that fit both my needs and my budget. The paperwork process was smooth and quick. Overall, a very professional dealership that truly values customer satisfaction

I really appreciate the straight-forward buying process I found at Napleton Schaumburg GMC. Thank you to Yiannis for answering all my questions! Best- Mark
