The Salesperson Mr.
The Salesperson Mr. Jacob Polk was super professional and dedicated to making the trade and sale happen. The interest was a bit higher than I wanted, but overall, I needed the truck to tow my boat and 5th Wheel RV/Toy hauler. The F-450 was perfect for the job and was in excellent condition.

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!

Ozzie and Belinda took great care of us.
Ozzie and Belinda took great care of us. 1. We had to trade in a car that was costing too much to repair. I put the information into the Echo Park system and Belinda called to ask further questions. It was that outreach that had us going to Echo Park instead of CarMax. 2. Ozzie was the salesperson who happened to be free when we walked in. He listened to what we wanted to do and made a couple of good suggestions. Then one test drive and we were ready to buy. The dealership honored the trade-in value and even added $250 to it, and altogether that helped pay for the warranty that we purchased.

Made 2 trips to Group 1 Buick GMC North.
Made 2 trips to Group 1 Buick GMC North. Interested in a 2026 Denali. Met Jarvis, my salesman, on first trip and felt very comfortable with him. He is laid back and not pushy at all. Told him what I was looking for and had two vehicles to trade in. I was satisfied with trade in values. Found the truck I wanted, color and interior. Was satisfied with the price quoted and purchased the vehicle. Probably the smoothest transaction I have ever had. Highly recommend both dealership and Jarvis!

I called in regarding a special coverage for my vehicle
I called in regarding a special coverage for my vehicle and was connected with George Avila. George was very informative, polite, and a pleasure to work with. He scheduled me an appointment and communicated with me throughout the entire process. While having to take my car in to be serviced was an inconvenience, he made the process so seamless that I forgot it was even an issue to begin with. My vehicle repair was completed well before the estimate I was given, and he even gave me great advice on future repairs. I also learned that they price match tires which is why when I?m ready to replace them, I?m going to reach out to George and give them my business.

it was time for my annual check up and stop by to see my salesman, Brad Biondo, who had emailed me an assessment of my 2020 GLC. I was just there to say hi but I left with a 2026; Ha- that wasn’t the plan. I am so impressed with the upgrade in terms of performance and attributes. Brad is super knowledgeable, reliable, and has integrity. Overall it was a fair trade.
