You see my advertising brilliance at work there. With the humorous approach the prospective buyer is disarmed to a degree, and really without knowing it. He's already trusting me because I'm comfortable enough to make a funny. I'm not forcing anything, I remain casual, there are no tricks, etc.
Next - and this for the younger buyers - I trigger subconscious response to an array of masculine symbols and subtexts. Mad max, the punisher, machine guns, military laboratories, etc.
Every buyer under the age of 25 is going to respond to this in a more favorable way; he's going to see himself in that blue jacket on that bike... and when he rides he becomes mad max or the punisher. I put this reverie into his mind.
