New and used 2026 GMC Acadia SUVs for sale near O Fallon, MO

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.

Great vehicle. Has great features and it is a very smooth ride. It is quiet on the road. Great gas mileage (over 28 mpg combination town and road).

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!

Awesome your staff is the best I've ever !!! Will always you BELLEMANN its literally the best customer service group I've seen Worth the extra mile to get there!!!

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.

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!

Brought my daughter to look at a new car. Put her in touch with Brook Winter. She walked away with a new GMC Arcadia. She is so very happy with her new SUV. She also was so pleased at the service she received from the time we entered the door until we left 3 hours later. We now have 2 Cadillacs and now she has her SUV. Will always recommend to someone looking to buy.

Great Place. Nicholas had such good customer service, Thank you. These guys know what they are doing in a friendly relaxed way. Not only the service is expert and fast, price is fair. They take time to educate you. A Friend recommended them to me, and I am passing this along. Thanks

We just replaced our 2022 Buick with a 2024 Buick Encore GX. Vivek Abraham is very helpful and does a wonderful job as a sales person. Crystal Mc Elroy is a wonderful sales manager and she is the reason we keep going back for more cars. The entire staff is helpful and we had an easy buy. We do our service at Suntrup Buick GMC too They have been very fair on tires and overall maintenance for our cars over the last 15 years.

I made appt. For recall parts however after making that appointment, and leaving car there for 2 days, was told no parts for repair available. They are available in Florida so it appears I should have had it done there. Bought two cars from this dealer and have always been pleased until now.

Jeff Bess listened to my needs and help solve my problem. As always Suntrup and Jeff gave me great service and assisted me in every way. I highly recommend both Suntrup and Jeff Bess. Thank you for your assistance

Hands down the best buying experience I ever had, Paul Johnson and Frank in Finance were extremely easy to work with, I felt it was going to be a great experience from the moment I walked into the dealership and was greeted. hanks Guys for making it easy!

Suntrup is an exemplary dealership in both sales and service. I will continue to use their service and will work with then again if/when I need a new car.

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.
