NADA is low retail on a Ford 30V no 30DL listed was $24,614 and avg was $29,658 that's for here in Washington State. Tires, belts, hoses, roof, look for delamination, water damage inside, hopefully service records. If not records and you are looking at $3000 to $6000 for improvements. Not sure what that would translate in Alaska.
