I had a great experience with salesperson, Steven in
I had a great experience with salesperson, Steven in March 2025. The other staff that I interacted with were really good and helpful too. I didn’t feel pressured. I appreciated that they didn’t try to turn it into an all day process. I purchased the specific used vehicle that I had been searching for online. This was the best experience that I have ever had at a dealership. I highly recommend this dealership.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Exceptional Experience at covert cdjr
I recently had the pleasure of purchasing my dream car at COVERT CDJR , and I am thrilled to share my exceptional experience. From the moment I stepped foot into the dealership, I knew I was in for something special.

First and foremost, the dealership's staff was incredibly professional, knowledgeable. Tony exceed my expectations in terms of his expertise, but he also displayed a genuine passion for his work. His enthusiasm was infectious, making the entire car-buying journey exciting and enjoyable. Tony's ability to make me feel like a valued customer and his unwavering dedication to ensuring my complete satisfaction were truly remarkable. Beyond the initial purchase, Tony's commitment to post-sales support has been exceptional. He has continued to be available and responsive to any questions or concerns that have arisen. Tony's willingness to go above and beyond to address any issues showcases his dedication to fostering long-term relationships with his clients. Their expertise and genuine enthusiasm for their work made the entire experience enjoyable and stress-free. Moreover, the dealership provided a comfortable and welcoming environment. The showroom was immaculate, showcasing a wide range of top-quality vehicles. I was impressed by the attention to detail, as well as the dedication to maintaining a clean and inviting atmosphere.

Their expertise and efficiency made the paperwork hassle-free, allowing me to focus on the excitement of owning my dream car. Finally, I cannot praise the post-purchase support enough. The dealership's commitment to customer satisfaction was evident as they went above and beyond to address any questions or concerns I had. Their dedication to ensuring a smooth transition and providing ongoing support truly exceeded my expectations. Overall, my experience at COVERT CDJR was nothing short of outstanding. Tony is the best salesman ever. Definitely earn my trust and i will only buy car from him. I highly recommend them to anyone in search of a new vehicle. Their professionalism, expertise, and customer-centric approach create a truly remarkable car-buying experience. I am grateful to COVERT CDJR for making my dream car a reality, and I will undoubtedly return for any future automotive needs.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great service from Gulsah in Used Cars
We just bought my son's first car, and Gulsah in the used car department was amazing. She was very patient, transparent and honest with us throughout the entire process. She ever pulled some additional information for a similar car we were considering at another dealer. Her sales manager was straight forward and not pushy as well. I've had some bad experiences with their service department in the past, but our most recent interaction with Gulsah and the used department couldn't have been better.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

We recently purchased a used King Ranch Ford truck from
We recently purchased a used King Ranch Ford truck from Covert Ford Hutto and had a terrific experience. Travis Etie, our sales person, was professional, courteous, and diligent in making sure the car buying experience was enjoyable. Although we had a slightly higher offer on our trade in from a national online dealership, we felt shopping local was a better option. The local companies like Covert employ many people in the area and its important to keep our local economy vibrant. The Covert price point on our King Ranch Truck was unmatched. We are thrilled to have gotten such a great deal! Covert Ford-Hutto has definitely earned our business from now on. Shop confident, shop local, shop with the best in the Austin area, shop Covert Ford-Hutto!
