Austin Chapman is one of the most wonderful people I have
Austin Chapman is one of the most wonderful people I have ever met. Buying a car from him was a completely pleasant experience. He went above and beyond to make sure that I was happy. My happiness was so important to him that he again went above and beyond. He is a great asset to that dealership. Very impressive young man. Extremely professional, extremely polite, extremely compassionate, and absolutely loves his job and what he does. He made a difference for me and I hope that he makes a difference for many more. Thank you, Austin, you are amazing!
