She was very thorough in showing me around the car and its features. I ended up getting a new car in the end and it greatly exceeded my exoectations going in. Abe was very hands on with working with the banks to get me the best interest rate and very friendly. Daniel was super supportive in the end and helped finalize the numbers ... Read More

Went to Bill Kay without an appointment after being disappointed by a competitor. Jordan came right up and was willing to help us out. He carefully went over the package options and pricing of each vehicle we were interested in and his manager Abe was amazing at figuring out deals and getting us where we needed to be with the monthly payment. I would recommend!

I purchased my 25 GMC Acadia at Chevy dealership (who shall not be named) and they dismissed my driver side window issue while still under B2B warranty. Took my Acadia to Bill Kay and spoke with service and with the tech and they were able to pinpoint the issue in no time. I'll be going back to Bill Kay for my future GMC needs.

We had an amazing experience at the dealership thanks to Marco Saldana! From start to finish, he made the process of buying our new Yukon smooth, easy, and stress-free. 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. We highly recommend asking for Marco Saldana if you’re looking to buy a vehicle — you won’t be disappointed!
