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

Walter Washington was excellent. Very nice and kind. I would recommend him to all family and friends.

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.

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!

Best kind of dealership. No pressure sales and mindful of your needs as a customer. We will definitely be repeat customers.

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.

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!

Great experience service Joe is helpful and very friendly would recommend him to everyone. Dealership is very clean and waiting time is always very short for normal service work

Loved the personal attention! Christy Thorton knowledgeable and professional! She was able to help me figure out the best car within my budget and to fit my family's needs

Everyone from Joel in sales to Zach in finance was amazing to work with. They made sure I understood and was comfortable every step of the process of buying our new car.

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!

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.
