I'm 70 years old, and I don't think I'll be around to see much appreciation of all the spare parts I have. I hear of all these prices that stuff brings, but I haven't been able to sell much. When I got to the scrap yard, I know I will come home with a little money. I was a licensed salvage dealer for many years, and a bumper pull trailer trailer full of short iron brings between $800 and $1,000.
