Has anyone ever found a factory mistake?

From my many years of 69 Camaros:

Custom interior rear trim panels on std interior car
Full dash woodgrain on a std interior car
Black D96 stripes on one side, white on the other
6/7 tach in a L35 SS
ZL-1 with an E78 x 14 tire pressure label
Missing trunk lid Camaro badge on D80 cars
Mis-stamped VIN tag ‘123339N’. I haven’t seen it but there is supposed to be a COPO with a convertible VIN ‘124679N’
Several body tag errors: build dates of 09, 051, 061, NBR instead of NOR. Convertibles with no X code are common.
