This is comical. It never ceases to amaze me what people will argue and defend. When the ego is convinced, it is correct it will argue its point of view until death. You should have asked him how much he would be willing to pay for the first million mile car. You would throw in the secrets for free if the price were right for the car. No point in arguing back when someone believes they are right. I just try to help them along so they can realize the truth on their own. He would be sitting behind the wheel staring at the numbers when it hits him that he doesn't own the first million mile car.
