many hundreds of years ago, [in the early 70's] my one buddy and i were at an auction and were looking at a car we thought seriously about bidding on[i can't remember what it was]. as we were looking, some old guy poked his head between ours and said : "cars with bondo are unsafe.......". never said another word. both of us looked at that old guy who never made eye contact with us, then looked at each other. when we looked again, the old guy had vanished ! we never saw this guy before, nor did we see him again at that sale, or others we attended regularly over the years ! we still talk about that [strange !] encounter to this day ! spooky indeed ! just a personal experience that will never be forgotten.
