New and used 2026 GMC Terrain SUVs for sale near Lake in the Hills, IL

I have never been happier since I bought my Buick at The dealership in Barrington Illinois Tim McIntyre was our salesman and Dave the manager Patrick in the finance department Went far above any expectation I had for any dealership we had been looking for a car for several months I’ve never bought a Buick It truly is The best car I have ever owned This dealership Made this purchase so enjoyable I recommend them to oeveryone

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

The Team that my husband and I worked with Dillon, Tim & Dan, were all very helpful and courteous. We had a certain price point and they managed to get us very close to where we needed to be AND we got the car we really wanted. Buying process was seamless, communication was great, and customer service was wonderful. This was our second purchase with Haggerty and we highly recommend!! Thank you

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.

Made a online appointment came in and they did a oil change and tire rotation. Happy with the service.

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.

Overall, the service was professional, informative and understandable from beginning to end. I came in explaining what I was looking for and that’s how it was through the process.

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.

The Marquardt experience was fantastic. Our sales rep, Fiona, was very knowledgeable and provided world class service. If you are considering a vehicle from this dealership, we highly recommend her.

Kevin was very helpful and gave me a deal on the Sierra 1500 that I couldn't refuse 10 out of 10

Mike R was our sales consultant. He did a terrific job explaining everything in addition to helping us with creative financing. Kudos to the dealership!

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

Excellent as well as timely service. However, was not told in advance that paying with Credit Card would have a 3% fee.

Great service! Mark was awesome. My appointment ended earlier than expected too. Plus a comfortable waiting area with coffee!

Bill was fantastic to work with! Whole process took only a couple of hours and everyone was very helpful. Pricing was transparent and they worked with me to get me best interest rate possible.

Have trusted this dealership for over 25 years. I wouldn’t think of bringing my 2 Buicks anywhere else. They only do necessary repairs which I appreciate and will give you a timeline as to what to expect down the road when it comes to doing work. They value you as a customer and do everything they can to help you in all aspects serving you.

Kim was incredible in helping me get my repairs covered by my extended warranty! Details of service were provided and car was ready when needed.

The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!
