Shout out to Melvin in the parts department who help me confirm the correct replacement part number for the telematics unit on my 2023 Bolt EV, and then went out of his way to special order it for me, noticing he could do so because my car is out of warranty. No other dealership took the time to hear me out, explore the issue, and find a solution. Melvin is that rare employee who is truly committed to delivering outstanding customer service. Thank you, Melvin!

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.

⭐⭐⭐☆☆ (3/5) I recently purchased a 2022 BMW X1 from Bill Kay Buick GMC, and while there were several positive aspects to my experience, there were also some issues that future buyers should be aware of. First, I want to recognize Jordyn Finley, my salesperson. He was professional, courteous, and worked hard throughout the process. He did everything he could to keep the sale moving, answered my questions, and stayed in communication. My concerns are not with him. I also want to recognize the finance manager.

Marco was professional, patient, and took the time to answer all of our questions without ever making us feel pressured. He truly went above and beyond to make sure we found the perfect vehicle for our family and got a great deal. His customer service and attention to detail were outstanding.
