This text was written by a man who has been buying and selling Special Interest vehicles from stubborn owners for over fourty years. It is not limited to just special interest vehicles but it is aimed at people who are dealing with stubborn owners of vehicles that have no intention of selling them. The most important item when starting your approach of a potential seller is to limit your dealings to one person, that person being the sole owner of said vehicle. "Too many cooks can spoil the soup".  Your overall appearance and  demeanor, upon your initial approach will weigh heavily on your ability to persuade. Do not wear or display anything pertaining to any club, fraternity or political orginization. While association might be a plus, there is always that chance that the would be seller has had a bad experiance with your group.  Limit small talk and get right to the point at hand in a tackful way. An often  overlooked item of the utmost importance is to pre-determine the maximum amount of money that you can pay for said product and have that amount on your person when you approach potential seller. If the situation is safe by all means show the actual cash to the person. That will separate you from the local "tire kickers". If  that person declines your offer and does not counter at that time, and does not forbide you access to them, then you need to back-off politely and re-think your cash amount and start the process over. If you haven't persuaded the person to sell by the second offer, or if a good relationship hasn't been established  at that point, then you just put the process on the back burner, or remember that sometimes cars are just, not for sale.
