Say you are in the business of used mobile homes.
¿What would be your main selling point? After all, it is what it is. When you are looking for a used mobile home, you know what you are going to get, snobby sales techniques won't add anything.
It is like doing a commercial for horse manure. "I sell horse manure, I stink the whole day and no woman will ever get close to me. If you buy from me, good, if not, I don't care".
