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

Gus and his crew were amazing. I bought this pickup off the internet, and they picked me up at the airport and 1 hour and 20 minutes I was headed home.

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.

Great service!I was picked up at the airport in a very timely manner.I recommend this dealership to anyone I meet that is looking for a vehicle.

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.

COULDNT ASK FOR BETTER SERVICE, GO SEE JOHN IN SERVICE TO GO ABOVE AND BEYOND YOUR 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.

From purchase to first service, no complaints. My purchase was smooth and easy with Nicki, and my service was fast and efficient with Heather! Thank You!

It was a great experience, I purchased the 2020 GMC Canyon Denali from Laura Buick GMC, I love the vehicle and service rendered by the dealership was incredible. They are a great dealership to patronize because they make their customers feel valued.

The salesman I dealt with, Rob Fulmer is one of the best. Strait forward, tells you how it is without any hidden surprises. He was honest, patient and very professional. He easily addressed all my concerns and questions and I would highly recommend asking for him to be your salesman. He was very quick in responding as I was inquiring about a car out of state and he made everything very easy and simple to understand. Out of the other dealerships I inquired about, it was like night and day. I ended up replacing my engine in my old vehicle, so I didn’t actually buy from here but everything was set up to go I just had to sign. He was honest about out the door pricing and the dealership he works for doesn’t try sneaking ridiculous hidden fees like some of these other places. This review is the least I could do since I pretty much wasted his time. Thanks Rob and sorry again!

Got transportation to home while repairs were being made with a nice guy. The repair was not as scary as I thought it would be.

Justin Scheaffer supported my acquisition of a 2025 GMC Denali truck with total customer care in mind. From finding the exact vehicle I wanted to it delivery, Justin was there, front and center - An Outstanding job; definitely a go-to professional who gets my highest rating!! Thanks Justin - Will stay in touch!

As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!

The customer service at Dave Sinclair Buick was fantastic! They had a lot of work to do on my vehicle. The work was flawless. The level of communication during the whole process was superb. Eric in the auto body shop showed what excellent customer service should look like. I cannot thank them enough for the level of service the team provided.

Nicki was wonderful, I will recommend her to everyone I know that are in the market for buying a vehicle. Jarrod was also fantastic to work with. Both very personable and made the process very pleasant when it had been made dreadful from trying to deal with other salesmen at other dealerships. These 2 were excellent. I've never had a better car buying experience. I'd been to 4 other dealers who wouldn't budge on price for the same vehicle. I was able to drive my brand-new car off the lot for $6000 less than the competitors offered WITHOUT a single haggle!

Nikki was extremely professional and knowledgeable about the trucks. The buying experience could not have been easier, and I never left South Carolina! My new Denali Ultimate gets delivered today at 5!

Very helpful staff. Absolutely no pressure to buy from Corey during the early phases of my shopping . Visited multiple dealers trying to find the right vehicle. When made decision on vehicle Corey and Steff did all the work. Online questions answered almost immediately. Even stayed late to accommodate my schedule. No hassle buying process. Made the 50 mile trip well worth it. Will definitely look here when in the market again.

Easy process. Dmytro was very helpful and accommodating. Follow up was timely. Found the car I wanted online, submitted a request for information, received a call back immediately.

Everyone at the dealership was amazing! They answered all of my questions, made me feel comfortable, and confident with everything! I definitely recommend this dealership to anyone looking for a used or new car.

Tyreese listened to my wants and even though my initial choice sold prior to my arrival, he found me a better option. He was very knowledgeable about the cars features which made me love my car even more.
