Blake was great! We were in and out in a couple hours. He stuck to his word, listened to us and was friendly and engaging. Never pushed us about any decision. Our fin We were in and out in a couple hours. He stuck to his word, listened to us and was friendly and engaging. Never pushed us about any decision. Our finance guy, Jarrod, was a different story. Once we refused any extras he basically threw a fit and barely talked to us the rest of our time he was with us, after he questioned us on why we made the decision we made instead of respecting it. Not a great way to end the experience. Blake gets a 5 stars! Jarrod needs to let sh;t go. 🤷🏼♀️ More

From the minute I arrived on the car lot I felt welcomed and not pressured at all. I was extremely comfortable around my salesperson Blake. He was so knowledgeable about all the vehicles and was not trying and not pressured at all. I was extremely comfortable around my salesperson Blake. He was so knowledgeable about all the vehicles and was not trying to push me into buying a car. The sales manager was very friendly and helpful. And the finance manager did not try to pressure me into anything that I was not comfortable with. It was truly one of the best experiences in car buying that I've ever had and if and when I need to I will go back to O'Fallon GMC!!! More
