Just like any mechanical item that has not been used for years,
maintenance and care will show and increase it's value. If it has been left abandoned in a back yard and it's full of field mice, it's going to be hard to sell at any price. If it has been stored properly and is in good running condition maybe in the $4,000-$5,000 range.
