What a fantastic buying experience at Helfman Ford in TX.
What a fantastic buying experience at Helfman Ford in TX. We were shopping online, out of state purchase, and had the pleasure of working with Richard Baxley who went way above and beyond. He kept us informed during the whole process and even more important followed up diligently during the delivery and when we took possession of the vehicle. Of course he then followed up yet again. I tip my cap to the dealership and Richard on a great buying experience!
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!

I had an amazing experience working with Trevor when purchasing my Ford Explorer Platinum! From start to finish, he made the entire process smooth, stress-free, and enjoyable. Trevor was incredibly knowledgeable, patient, and honest ? he took the time to answer all my questions and made sure I was completely comfortable with my decision. He went above and beyond to find exactly what I wanted and made sure I got the best deal possible. I couldn?t be happier with my new SUV and the top-notch service I received. If you?re looking to buy a vehicle, I highly recommend asking for Trevor ? he truly delivers five-star service!
