I had an horrible experience with McDavid Honda of Frisco. I am not sure how this dealership was awarded best dealership award. I was at the dealership on 09/19/2016 looking for a new civic. I made a deal with one of the managers, gave a deposit of $500(around 9pm) and told them that I would come and get the vehicle on weekend. So on weekend I go to get the car and the manager with whom I had made the deal was no longer with the dealership and new car sales manager said he cannot honor the deal since pervious manager did not put the deal on paper even when one of his associates who was present during the time of the deal confirmed him about the deal. This dealership is not going to get my business nor am I going to refer any of my friends/family to this dealership.
