I am pretty sure you just turn your money over to a scammer who just disappears with it. Since it is stateless and a libertarian dream, nothing can be done. So, congratulations!

This can be a good lesson for anyone buying a vehicle. There are 3 items in a sale: the vehicle, the title, and the money. No one person should have all 3 items. Also, do not buy cars from people without the title, or title complications. These type of sales are a risk, and unless you are willing to lose the money, stay away. I always like to do a pre inspection, or have someone I trust do one, as that is a good way to mitigate the risk.
