Back many years ago during my career as a Ford dealer parts manager,
we used to have our driver stop at other Detroit area dealers and they would have a list of parts needed that day,
they would have that dealer check to see if they had any of the parts on-hand.
(This was before the "part locator" services used now).
We would add fictitious part numbers like C9ZZ-6321609-A to the list to see if the dealer would catch it!
( C9ZZ-6321609-A = LH vent window frame for 69 Mustang fastback).
I see a new revenue stream possibility on flea-bay ??
