EVERYONE at Bill Kay Buick GMC was so friendly and helpful! Christian helped me first through Facebook Marketplace, and when I arrived at the dealership, Dylan was my sales representative. Dylan was such a nice, friendly young man. He was never pushy, which I really appreciated. After I bought the car, I started getting a little nervous because, well… it’s a big purchase! 😂 Dylan was so calm and reassuring and kept reminding me that I had made a really good purchase. Now that I’ve driven the car home… I LOVE IT AND I’M SOOOO HAPPY!!! ❤️🚙 Thank you to Dylan, Christian, and everyone at Bill Kay Buick GMC who helped make this possible. I truly appreciate how kind everyone was throughout the whole experience. May you all be blessed!!🙂
