back in the early to mid 70's a friend and i were at the auto auction we attended on a weekly basis, and looking at a car we were interested in bidding on. while we were inspecting it, an old guy popped between us and said in a quiet, no nonsense voice : "cars with bondo are unsafe !" then he just disappeared, leaving us to look at each other as, "did this just happen ?" we looked around, and he was just GONE. no trace of him. never saw him during the rest of the auction, and never saw him again ! we still talk of this event to this day ! so just take that as a warning...........
