I once looked at a 52 Singer 4AD that had sat in a field for somewhere around a dozen years. Needed everything, wood, interior, cracked block due to crank having broken at speed. I offered $100 for it. Guy wanted $20k telling me he'd seen one for sale in Hemmings for that price. I noted that this was restored and running, not a basket case. Got run off the property. Car sat until he dies years later and was scrapped by his kids.
