Probably about 3X its value. From your list below you are looking at
about $8,000-$9,000 in services and parts to get it camp worthy - a lot
more if hire it done or decide to fix those skin dents.
A more realistic price is in the $900-$1300 range, and this time of year
it should be on the lower end - especially if on the east coast.
