Ruben was very polite, helpful and professional. He went above and beyond to help me. He even washed my truck before I left. He made sure that everything was taken care of before I left.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!

True patriotic dealership
I personally want to thank Gene, Jacob and Presley for taking a personal interest in helping a disabled combat veteran with the purchase of my new truck. What a true patriotic dealership family. Gene, Jacob and Presley went out of their way to make sure I was given the best deal possible along with making me feel important. On top of receiving the best care and deal, they are also going out of their way to make sure my vehicle has the modifications needed for my disability. God bless the entire Town East Ford family.🇺🇸
