New and used 2026 GMC Terrain for sale near Algonquin, IL

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.

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.

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

10/10 experience. Definitely worth the drive to get the car I wanted. Brian was great! He got us the best deal on a brand new suv.

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.

Andrew Allen was amazing partner in my purchase so patient and great knowledge related to my Encore and Buick. The walk through was very thorough even providing me with his direct access for all future questions.

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.

On behalf of the purchaser: What a wonderful experience. Jarvis was very professional, knowledgeable, helpful and made buying a car amazingly easy. He resolved every issues and spent considerable time reviewing all the new features. He even put a lovely giant bow on the car for pictures, and gifted us with a lovely mum plant. Such a great experience without any issues! We highly recommend him and this dealership for purchasing a new car.

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.

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!

My 12 1/2 year old Volt is hanging in there because of the skill, knowledge, and great work by the team at Chevy Exchange. I called a few days before Christmas to describe a problem. They got me in the morning after Christmas. A part was needed so they kept my car and a nice young gentleman drove me home. He picked me up the next day when the car was ready and the car is working better than it was before the original problem occurred. Many thanks to all of the great team members at Chevy Exchange!!!!

Thank you to the service team for your getting me all set for my roadtrip!

The dealership responded quickly via email. Did not end up looking at the vehicle. Appreciate the quick response.

From originally purchasing my car at Haggerty to having my car serviced at Haggerty, my experiences have all been positive. Everyone is friendly and answers all of my questions. Work is done well and on time.

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

Super honest deal. Used car as advertised, no surprises, no pressure. They detailed it for us while we did the paperwork.

Marquartd of Barrington is an amazing dealership because of their integrity and great customer service! I bought my new car 2017 and have relied only on them to maintain it.

If you're looking to purchase a new or used vehicle, I highly recommend Arlington Heights Buick GMC. This was my first time purchasing a vehicle from a dealership and they were great. From the managers and salesman, all the way to the financing department and cashier, everyone was super nice and helpful. Keep up the good work. I will definitely be back in the future! Thanks again A.H. Buick GMC!
