I had a great experience at AutoNation CDJR Katy.
I had a great experience at AutoNation CDJR Katy. Rafael was my sales rep and he explained everything clearly, answered all my questions, helped me feel at ease about any doubts I had regarding making a big purchase, and worked hard to make sure I felt comfortable with the best deal they could possibly get. Gerardo in finance was just as great. He was knowledgeable, very easy to work with, and even made signing paperwork fun. The whole process was smooth and efficient! But what really stood out to me from this dealership was the degree of professionalism and honesty. When an issue came up, instead of brushing it off, they were upfront and fixed it quickly. That kind of integrity and proactive protection of customer trust is rare. And it?s the reason we?ll definitely come back here for my husband?s car and my next car, as well as refer my friends and family, because outstanding customer care like this deserves to be shared and celebrated. If you want an honest dealership that treats you with respect, values transparency, and truly cares about its customers, AutoNation CDJR Katy is the place to go!

Amazing Service Department
Joe Mayer Ford is the best dealership I have ever been to in Houston, TX. After calling the Tomball Ford I purchased my car at, about a window that would not roll up I tried Joe Myers. They looked at my vehicle with hours of my car being dropped off, compared to many other places telling me they would not be able to do the same for about 4 days. Jordan in the service department expedited the part and I had car ready a full day early! Simply amazing and the most helpful service time I have ever dealt with.
