Kaiser Buick GMC, DeLand, Florida
Michael in service department is just awesome. He takes care of us as if we were family. I wish everyone would deal with us like that. Some businesses act like we are bothering them for them to take our money. Anyway, I could go on and on. Even Pete the sales manager is a great guy, and greets us in the waiting room like a friend. This dealership is what you strive to have represent GM. I am retired US Navy and appreciate respect and curtesy. Thanks Del

I ask a lot of questions, challenge any information that doesn?t make sense to me and expect honest, timely and transparent communication from the service provider. Latonya and the Orange Buick Service and Parts team exceeded my expectations! This was my first visit and happy that I have a trusted partner with my new-to-me Yukon XL.
