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.

I purchased a GMC Terrain from their dealership. Everyone was great to work with from calling to confirm availability, setting an appt. for the test drive, to purchasing the vehicle. They had a variety of vehicles to choose from making the decision difficult. Thank you for a great experience.

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!
