We purchase a truck from them and when I took it back because of an issue the manager interrupted the conversation with the salesman and began YELLING at me. If I had been a man, he would NEVER have spoken to me the way he did. NEVER will we go back to GMT. The salesman, John, was a very nice guy. The manager....wow...never again will I subject myself to that kind of verbal smart-mouth attitude from anyone. 4 stars to the salesman, John, for his friendliness.
