Called the evening before to set up an appointment to look at a car the next morning,
We arrived and Kim the salesman tells me someone is already buying the vehicle I had come to look at! He Tells me a lot of people say they are coming by and never show up! Well i am here now what? I asked to speak to a manager and he tells me that "they do not have a used car factory that they can order another one like it!" No kidding, how much more insulting could you be? Then they had the nerve to tell me the other sale might not go through and to wait! I have never seen such unprofessionalism. Thanks for showing your true colors before I spent thousands of dollars and could just simply walk away! Really, thanks!
