Oh, believe me, i really don’t understand it either. And without knowing exact mileage, storage conditions, and getting to look over known trouble areas, it’s impossible to make an accurate guess. The only thing I can base it on is what I see people asking for them by description only compared to what I think it would actually be worth by a description. I am expecting my answer to be off because of the unknown, I just pulled the middle number for an unrestored example with normal wear and tear.
