New and used 2026 GMC Terrain for sale near Wheaton, MO

I went to MD Buick GMC a couple of months ago to inquire about purchasing a 2025 Hummer EV SUV. We discussed several options and the staff was extremely knowledgeable about EVs, especially the Hummers. Cole (sales rep) was amazing to work with! Great guy! Passionate about what he does and truly cares about his customers! Grant (sales manager) actually took us on a test drive of the SUV to better inform us of its capabilities! The test drive was a blast! He took his time to answer all of the kids questions, was patient and really made everyone feel a part of the process! When we got to the negotiating, Todd (GM) made sure that we got the best deal possible! He was super easy to work with, made sure we understood everything, and got exactly what we wanted. Austin (Finance) took great care of us as well! Again, made sure we got everything we needed, went over all the numbers again to make sure nothing was missed, and helped us get all the coverages we needed/wanted! Ryan (service manager) was extremely helpful in making sure we got the accessories we needed, like a home charger! He was super informative, and took great care of us! Everyone was truly amazing to work with throughout the entire buying process! The next time I am looking for a vehicle, I will absolutely go back and let them help me find the vehicle I want! I wish every dealership conducted themselves as these guys do! I would probably buy cars more often! I almost forgot the best part!! It didn?t take all day to buy a car!! They were very respectful of our time, took the time needed to ensure we were extremely happy, got exactly what we wanted, and made the process as efficient and painless as possible!! It was truly the best car buying experience I have had! The whole family loves the new Hummer EV SUV!!

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.

I was absolutely amazed at the professionalism of the staff at Mayse. William and Stan were so accommodating but not pushy. I would recommend them to anyone and definitely will be back. Thank you for such a pleasant car buying experience

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

Lee was fantastic to work with and was a wealth of information. The experience was quick and didn?t feel like a waste of my time.

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.

Ehren and Laz were great to work with from start to finish. We experienced top notch service with no pressure to buy. We took off work to come to Aurora and appreciate their prompt attention and being ready when we arrived. Also enjoyed the conversations while there. Get to know Laz and Ehren, you won’t regret it.

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.

My experience was Low pressure, courteous, informative. Tyler provided a great service, even after hours to keep me informed. New truck purchase was made easy.

As usual, great service and experience, Had my 2019 Buick Enclave's oil changed and tires rotated. Will definitely consider McClarty Buick when looking to trade vehicles in the future.

Excellent dealership to work with. Would definitely use them in the future. Smooth transaction and process. Love my new Yukon xl. Great selection of vehicles available

Mayse is the best place to buy a car. John Kieney our sales persons is super professional and polite. They also have the best pricing and no hassle experience.

Mayse is a great place to buy a car. Simplified and straightforward process. No surprise fees or costs. Good people to work with.

have purchased 2 pre-owned vehicles from Mayse. Live in Kansas City. What I like about them is they had gone thru the vehicles and fixed all the problems before they even sold the vehicle. we settled on the price, and I told them if it was as clean as they said it was, I would take it. both times went down, inspected and less than 2 hours drove off. cannot compline about anything. first car lasted 10 years and had over 275000 miles before I decided, it was time for a different car. 2nd on purchased 3 years ago. driven 50,000 miles no issues.
