Beautiful car as pictured.
Beautiful car as pictured. Needed a number of things addressed that you could not see in pictures. Manager was very persuasive about making sure all the things that needed attention would be addressed but I was concerned that there was more than I could see in a short drive and inspection. Would need some more time to make sure that the vehicle was as advertised. Just not comfortable completing purchase Still a beautiful vehicle, was very hard to not complete purchase.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Wonderful experience! Our salesman Ricardo Magana was knowledgeable and easy to work with. He made sure everything was working on our car before we left the dealership. It’s our daughter’s first car and we feel she has a good reliable vehicle.

First time customer at this dealership.
First time customer at this dealership. I was met promptly by a service advisor and after the preliminary paperwork, was shown to the customer lounge. Bright and clean with comfortable seating and refreshment options. My car was ready on time, sparkling clean inside and out. This dealership does a great job. I left impressed and satisfied. I'll be back.

Exceptional Service!
I have purchased 3 vehicles from Honda of Fort Worth and am always greeted with exceptional service. Everyone I’ve worked with has always been thorough, helpful, and made sure we knew what was going into our purchase. I recently bought a 2023 Pilot and love the vehicle. Jesse did a great job communicating with me, and making sure all of our information was correct.

Great, knowledgeable salesman Nick
We visited Five Star Subaru to look at SUVs and were greatly pleased with the customer service we experienced. We had Nick immediately greet us inside. We let him know off the bat that we were not in a place to purchase same day and he was extremely pleasant and still gave us his full attention and guidance through the entire process. He was very knowledgeable regarding the Outback and Forester and we really appreciated the fact that he personally owns both of those vehicles. He answered all of our questions. I can truly say that we will be purchasing a Subaru a lot quicker than originally planned because of his hospitality, pleasantness and expertise.
