We at O'Fallon Buick GMC are so excited to be joining the O'Fallon community! While our roots are in our hometown of Greenville, SC, with many years of experience and three generations working within our family business, we knew that it was time to expand. In January of 2019, we had an opportunity to travel to O'Fallon, MO and the surrounding areas and instantly knew that we wanted to join the O'Fallon ...

Having purchased numerous cars, trucks, and SUVs over the years, we can confidently say that this experience surpassed all others. Devan Walls, truly living up to his title as the "car matchmaker," made the entire process seamless and enjoyable from start to finish. His expertise and keen understanding of customer needs led us to explore a vehicle we might not have otherwise considered—one that turned out to be the perfect match. Devan’s commitment to service excellence was evident throughout every step, ensuring a stress-free and rewarding car-buying experience. We highly recommend Devan and the team at O'Fallon Buick GMC for anyone seeking professionalism, knowledge, and exceptional customer care. Read More Read Less

O’Fallon Buick GMC was great at getting me the car I wanted. Having been in once and having worked with Devan, I was most comfortable calling him when I saw the vehicle I liked pop into the inventory on-line. I made a quick call to Devan and he had it waiting for me upon arrival 30 minutes later. He shared all the pertinent details, we drove it, and the deal was done. Great experience!

Was in the area and decided to drive through the lot and happened upon a very nice man named Zach. He was very patient and realized that I wasn’t quite ready to buy a new car, but I was amazed at all the information that he was able to provide and how he made the conversation very comfortable. I’ll definitely be looking up Zach in the near future when I’m ready to buy. I’ve already recommended him to a couple of my family members and coworkers and hopefully they’ll buy a car from him.

I was in the market for a new work truck and O'Fallon came up as one of the top rated dealers with the best discounts in the nation, so I gave them a call and got Paul as my Sales guy. Paul and I went back and forth about the truck and my trade in over a few days. I'm from WI and never bought a vehicle from another state. Paul assured me they do this all the time and there should be no worries. We made a deal on the truck, Paul pulled it off the sales floor and put it into service to get ready for me to pick up the next day. The next morning, 5 hours into our drive Paul called to drop a bomb, a manager the night prior, took the truck out of service and sold it. Crazy. Since we were almost there, we continued to the dealer to see if there was other trucks on the lot we would like. Paul met us at the door and was very kind and apologetic. They had another truck on the lot that was the same model but had a lot of "extras" I really wasn't into or needed. After some negotiations we worked out a deal and I am happy with the truck. At one point we met with Richard the GM. Richard came off as very arrogant and unapologetic. By self admittance, he was the one who pulled the keys the night before and sold the truck that was reserved for me. We never got an apology from him. He was in "sales" mode the whole time and it was a bit aggravating. 100% of the reason this review is getting 5 stars is because of Paul. He's a down to earth, straight forward guy. Johnny on the spot throughout the whole process. In the end, we left happy. We would do business with O'Fallon again. Also, Micheal Johnson is one cool dude! Read More Read Less

Exceptional Experience from Start to Finish The entire car-buying process was incredibly smooth and hassle-free. The team worked closely with me every step of the way—even up until the very last minute to ensure everything went perfectly. Their dedication to customer satisfaction truly stood out. I would absolutely return to purchase another vehicle in the future and highly recommend them to anyone in the market for a car. Read More Read Less
