For every 10 prospects that you meet face-to-face:
Two will do business with you no matter how good or how bad you are.
Two can not, or will not buy no matter how good or bad you are.
Six may or may not buy depending entirely on your interaction with them.
This is why everyone must be treated like a buyer. Give great presentations, have a great enthusiastic attitude, and close, close, close.
You should have two appointments every day. By appointment, I mean, a set time for a customer to come in to see a new car.
