New and used 2026 GMC Terrain for sale near Round Lake Beach, IL

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

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.

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 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

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

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.

Most pleasant waiting room anywhere and the friendliest service people.The mechanics always attempt to fix problems before they start. Also wait time ia always fair.

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.

Very smooth experience. Seann is an excellent young salesman. Darien will do anything to work with you. Erick, the manager is very accommodating. A++++ dealership.

I had the best experience buying my new Trax. Craig Winger was absolutely amazing. He is very personable He was great about what I wanted and did not try to persuade me in any way. Just a great guy and you felt more like he was friend than a salesman. The whole Lynch family was great. Tom and Dan were great also. Just a great experience for buying a vehicle, the best I have ever had. Craig thank you I Love my New Blue Trax. Would totally recommend Lynch for your next vehicle purchase. 10 stars and more

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

Great dealership. Easy going people, they take their time to explain everything you have questions about and try and help you anyway they can. Kevin was awesome to work with!

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 usually don't do reviews, but have to give a shout out to Jamie for making the process easy. I was not in the mood to buy a car and all I wanted was simplicity. Jamie understood that and didn't hassle me, which was the right call because I literally walked away from another dealership for being too pushy on upgrades and financing. I'm happy with my purchase and my experience with Jamie at Woody. Never thought I'd get a Buick, but it's super cute and I think I'll enjoy having it just as much as I enjoyed my last car.

Best experience I've had when purchasing a vehicle. Everything was handled quicky and professionally with no pressure to consider anything other than what I had asked for. I was completely satisfied and would recommend this dealer and my sales associate Larry.

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

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!

Always smooth and easy-going at Lynch. They take great care of us! Would highly recommend anyone in the market for a new or pre-owned vehicle.

Out in 45 minutes. Great clean service center. Service techs, Bob & Jon, are polite and professional. Car was parked right outside the entrance. Thank you for always providing a good experience. Jim Fus

Excellent service Professional service Quick service Polite customer service Excellent customer communication Very detailed repairs

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.
