ksteve, thanks for writing that up. I've actually gone that route in the past, but no longer have a car/truck to transport my bikes, so the lien sale is my easiest option.
A lien sale can be completed by anyone. Posession is the majority of ownership in this state, so you can claim storage fees, unpaid service fees, etc. and use those costs to file for a lien sale, which is contingent upon non-payment of those items. I believe there is a minimum time that you must allow the prior owner to pay the lien, but after that you can apply for a title on the vehicle.
Put more simpley, if someone abandons a vehicle on your property, and you charge a dailiy storage rate, then when the accrual of those storage fees exceed the value of the vehicle, you can apply for a lien sale. This method can also be used for bikes you purchase that do not have titles.
