The service department is a great bunch of people, Terry and Dave were super helpful.
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!

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 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.

I had an amazing experience working with George Strong at Hendrick Volkswagen Frisco! From the moment I walked in, George was professional, patient, and incredibly knowledgeable. He answered all my questions clearly, helped me explore the best options, and made the entire car-buying process smooth and stress-free. What really stood out was how transparent and customer-focused he was — no pressure, just honest guidance. He genuinely went above and beyond to make sure I was comfortable and confident with my purchase. I absolutely recommend George and the Hendrick VW team if you’re looking for a great car and even better service. Thank you, George, for making this such a positive experience!
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

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.

Easiest Car Purchase To Date
I was searching for a new/used car. I used Cars.com to search for a Toyota Highlander. Carmax in Ft. Worth, TX was one of my choices. The car shown online was EXACTLY as shown when I saw it-the pics and details provided about the car were so accurate, there wasn't a need for alot of "wheeling and dealing". I emailed Carmax regarding my interest, late at night. Not only did I receive an email within 1 hour, the next day I received a phone call from Mr. Ben Arbour, the person who would eventually sale me the car. He walked me through their process, got me pre-approved over the phone, so that all that was left to do when I got to the office was to get the trade-in value on the car I was trading, test drive the new car & sign paperwork to purchase. I bought a 2010 Toyota Highlander that was a 1 owner car with approx. 13,700 miles. I recommend Carmax to anyone looking to get another car. They were great!!! The customer service is GREAT!!!

Lori has Top Notch customer service and is an excellent communicator. She got all my maintenance taken care of, she suggested wiper blades which I had forgotten about and needed. I took advantage of the deluxe wash which was cheaper than my regular car wash and did a better job. She even dropped off my car to my doorstep free of charge. I'm definitely going to come back to this location! Thank you.

Great car buying experience
We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.
