I guess you have to just hang in there. I just bought a rare car, and it seems as if several people attempted to buy the car before the person I bought it from did (man that was a lot of words). Anyway, everyone was surprised when the car was sold, and I was lucky that the person that bought it was only looking to flip it for a small profit when he decided to start a new project.
The key I assume is to keep up with the owner without being a pest. And if I knew how to do that, I would have that Yenko!
