Yes, it should be saved, however, at what cost? You really have to want this car, and be ready to spend a lot of money to get it back on the road. A missing radiator can cost your $400 to replace, and who knows what glass is missing, and how much damage the weather has caused to the inside. With enough time, patience, and money, just about anything can be saved. I would expect that the seller would at least deliver the car to the main road. If you are going to need a roll back to get it, and have to cut a roadway through trees to get the truck to the car, that can get expensive very quickly. Keep in mind that once you cut the tree down, you are going to need a way to remove the tree, and have a place to put the tree. This means having a backhoe on site to do this work.
