“I cannot say enough good things about Walter Washington! He was my salesman at OFallon Buick GMC. It was a great experience dealing with him! He and the sales manager and finance guys go out of their way to help you! It was worth the drive to get my first EV truck and to meet Walter. He’s Top Notch! Thanks again Walter!”

“This is the second car I got here in the past year, if you come to this locations make sure to ask and see Roger he will get you what vehicle you want or even recommend what other vehicles that could accommodate you and your family and they will work with you on your trade in finance what ever you need Roger will get it done for you. That the reason why I went back the second time instead of going to other dealerships. 5 stars for customers service and good experience both times there”

“While I was shopping for my dream truck, at my job they were offering free charging to us employees. I went to go check out the Hummer EV and I felt like a General Motors engineer was walking me through the vehicle with Hakeem Daring. I don’t think there was a single feature or option he didn’t showcase or explain to me. He also showed me my dream truck which was a Denali Ultimate 2500HD. From the massaging seats all the way to the kicker soundsystem in the tailgate it couldn’t get more thorough than Hakeem. Absolutely loved my shopping experience with him and any time I ever am shopping GMC he is my go to!”

“Great dealership to purchase a new vehicle. Christy Thornton is truly a sales professional. Very professional in her approach and no high pressure sales pitch which I truly appreciated. The whole process was was very enjoyable for a stressful time in purchasing my new Encore GX thanks to her.”

“We had another great experience working with Vivek at GMC in O’Fallon. He took excellent care of us, as he always does. Vivek was very responsive throughout the entire process, answered all of our questions, and made sure everything went smoothly from start to finish.
We also love the new location where he’s now based. The dealership has a great snack bar and a playroom area for kids, which made the experience much easier for us as a family. It’s such a thoughtful addition for those of us who come in with little ones.
If you’re looking for someone who is knowledgeable, reliable, and genuinely cares about his customers, we highly recommend asking for Vivek. We’ll definitely continue working with him in the future!”
