When I had my tow service (Calif.) I was constantly doing lien sales on vehicles, mostly abandoned ones. The DMV required lien sales before any vehicle could be scrapped out or sold. The main reason for the lien sale is to let all parties of record know that the item in question is going to be sold for the charges against it. They then have 30 days to respond which also includes the current owner and pay the fees due. As the garagekeeper, I was entitled to reasonable towing and storage fees plus any repair charges. Most people would never respond, so depending on the vehicle's condition, I either sold it for the charges or scrapped it. In the end, doing lien sales involved time consuming paperwork, maintaining a storage lot for all the iron, and then disposing of unclaimed vehicles. Believe me, lien sales are not easy money. I would have rather had the owners pay me for my charges and take thier vehicle off my property. I've even gone so far as to offer free towing home (if the distance was reasonable) just to end the problem. Mike.
