Mark England is Dedicated! Shop Here
Usually, when you have a bad outcome, people bash the service provider, but not in this case. I wasn't able to get approved without a down payment for a car. But I would like to take out the time and Thank Marcus England from the upmost, for the outstanding customer service, he has been giving me for the past 2 weeks. If you ever need a car, with challenging credit, please contact CarMax Fort worth. Marcus and the fantastic Finance team tried very hard to get me approved. I didn't get a car but the Customer Service shows that CarMax out value in there employees. Thanks so much, I pray Gods Blessings at this place, and that y'all sale 75 cars this weekend. Y.Thompson

Overall, Vandergriff Chevrolet service dept.
Overall, Vandergriff Chevrolet service dept. did an excellent job on my repair. With an extended warranty, the repairs cost nothing. But if I do critique anything, is the trying to get me to spend $1,200 in new battery cables. There was nothing wrong with them.

Four vehicles and counting
I bought my first car with them as a teenager and last month, I bought my FOURTH vehicle from here. I have used them to finance in the past and they also made the trade-in process as simple as can be. Matt and Cole are very knowledgeable and very personable. They have always treated me with such respect and kindness and I will not buy a vehicle from anywhere except here. Everytime I come in, I have a different budget and different needs, but they always seem to find a vehicle that best matches me and my needs. Great guys offering a great service.

I can’t say enough good things about my experience at this dealership, and it’s all thanks to Jacob V.! From the moment I stepped onto the lot, Jacob was there to assist me with a warm smile and a wealth of knowledge about all the vehicles available. His expertise really stood out as he guided me through the options, answering all my questions and making sure I felt comfortable with my choices. What impressed me the most was his dedication to getting me the best deal possible. Jacob went above and beyond to ensure I was satisfied, and I truly appreciate the effort he put into making my car-buying experience smooth and enjoyable. I left feeling confident in my purchase and excited about my new vehicle! I will definitely be returning to this dealership, and I highly recommend asking for Jacob if you’re in the market for a vehicle. He’s a true professional who genuinely cares about his customers!
