What are they worth? There were 2 box cars on my wife and I's acreage when we bought it. I always thought they were kinda neat and we use 'em as extra storage, but I was always told that they are somewhat valuable, as well. Someone has offered to buy them now and I have no idea what price to ask. Ebay turned up a caboose that has a starting bid of $8500, with no takers, so that is of little help. Any ideas, guys? TIA
