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

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.

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.

Purchased a Camaro from 900 miles away. Anthony and Dan did a good job and made the purchase easy. They also assisted in shipping the car to me.

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.

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. They are trustworthy and truly care about the customer. Their work ethic and philosophy reflect heavenly standards. I will never go anywhere else!

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

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

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!
