I would suggest contacting the owner of the shop and discuss your intentions with him if you have any. If you don't try to work out a plan with him he has no choice but to put a lien on it.
A lien can be placed on the vehicle after due process is followed according to the law in which the incident took place.
A year
The lien is no longer applied to the vehicle when the loan is paid off. You can then get a lien release from the lender. As long as the loan has not been paid off the vehicle still has a lien on it.
Legally No. How can you sell something you do not own. As long as there is a lien, you do not own the vehicle outright. Go see the lender and get a lien release, if you no longer have a loan on the vehicle. Remember the lender is part owner of the vehicle until you make that last payment. If you clear the lien buy using the proceeds from the sale, you can guarantee a title within 30 days (required by law) to the new buyer. The lien holder will then release the title.
Until you pay it off. If you try to sell the vehicle, the mechanics lien will prevent you from doing so.
Forever Adding: I believe the questioner may actually mean to say - does the lien holder have to wait to sell it. Perhaps he doesn't understand that after repossession, it is then "their", that is the lenders, vehicle.
As long as there is a lien on the vehicle the lienholder has the right to repossess the property
90 Days
A lien can be placed on a property in the United States when a person owes a creditor a sum of money. In the state of Missouri, a lien can be on the property for ten years.
The bank holds a lien on the title of the vehicle. If you default on the payments, they can reposses it. This is a civil issue, and is handled as such. Unauthorized use of a motor vehicle is a criminal charge which doesn't apply to a civil situation.
A judgment lien is good for around 20 years in most jurisdictions. It must be rerecorded every six years in Massachusetts.
Until such time as all debts incurred for the purchase of the car are paid off
