How to buy a bike without title??

[Turbo Ghost]

I've found a bike on CL that was purchased from a storage auction. I called the county clerk and they said the last title holder had to apply for title. A friend said to buy it and post an ad in the paper for the previous owner to collect the bike and if no response to apply for a mechanic's lein title. That sounds a bit iffy to me since I was never contracted by the original owner for any services. I'd really like to get the bike but, the situation has me worried. I don't want to get stuck for the money and lose the bike. Has anyone here had any experience with this situation? Any help is appreciated! Thanks!
