Are You a Good Salesman Selling Used Cars?

In America and the United States, people have an idea that used car salesman are not trustworthy. And so this makes it very difficult to be a good salesman selling used cars now. If you might have good technique, but if the characters bad, eventually people stop trusting you. I agree with what Stephen Covey saying. He says an emotional bank account is a metaphor that describes the amount of trust in a relationship.
