New and used 2026 GMC Terrain for sale near Port Byron, IL

The sales team and management are amazing.!! Bought a brand new car from Calieb and he made this a great experience! All I had to do is come in and sign papers and I was out the door.. Thank you Calieb!

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

After several years of helping me keep my 2013 Tahoe rolling smoothly down the highway; Jay, Randy and the Key Auto Mall Team helped me select my next ride -- a 2023 Yukon XLT AT4. Customer service is first and foremost with this team. I recommend all my friends and family to give them a call. I appreciate their hard work and will continue to bring my vehicle for service because that department rocks too!

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.

Friendly and knowledgeable staff that were eager to help in any way possible with our needs.

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 couldn't be more happy with are recent purchase of a GMC Denali. Thanks to Jay for making the experience very easy and quick. Less than 2 hours and we leaving in are new truck.

Billion Auto in Clinton, Iowa, always take care of all my needs. There service advisors are great to work with. Definitely recommend.

I had a very good experience, had a very nice salesman by the name of Branson.B, he helped me out & got me into a vehicle that I like, he was very helpful, & upfront. So I will be recommending family & friends to this Davenport, IA location .

My salesman Branson Banks was supurb! He worked very hard to find the perfect vehicle for me! I definitely recommend Green Buick GMC for the purchase of your next vehicle - tell 'em Bert sent ya!!!

We purchased a 2023 GMC Acadia with the assistance of John Thomas, Sales & Leasing /JT and Max in Finance. To start, John made the process painless and easy. He answered every question we had. He was very patient and kind. We had a wonderful experience. Max with Finance was very nice. He also answered all of our questions as well as being patient and kind. Both of these gentlemen provided excellent customer service. You could tell they both enjoyed their job. Thank you so much!

Quality of used vehicle was what was advertised. Salesman were friendly but one was a little pushy to close the deal. My payment is higher than I originally wanted. All in all I would buy there again.

Worked with JT and Max for the purchase of a 2020 GMC Acadia. We went in with a set monthly payment idea and they worked with us until we got to where we wanted to be. 10/10 customer service experience! Even if things wouldn’t have worked in our favor, we would have left knowing they did everything they could and actually care for their customers! Highly recommend!
