I hate it when people just throw stuff out in the yard or paddock, leave it to rot for a few years, then try to sell it for top dollar. I went looking at a pair of "leather" seats, and old mate takes round the side of his shed where they have been rotting for who knows how long. So not only are the frames completely rusted out, but they actually had vegetation growing in them
and he wants over $100.
Worse it when something breaks down, so they dismantle it, throw it out the back of the workshop to rust for a few years, then try to flog it by claiming it was still working.
I know that if I'm buying something 2nd hand it will have issues, but I like to know what I'm buying so I know if it can be fixed.
