Unusual stickers on window

[conesare2seconds]

Has anyone seen stickers like this on their windows? The roadside assistance sticker, I?m familiar with, it?s the other two.

The font and layout looks like GM but I?ve never seen them before. The car isn?t a low production number for the year and there?s nothing on the Carfax to suggest something like press fleet - they?re mostly a curiosity.

If they were there I would have peeled them off.

Not yet. The GM logo interests me. Have ordered a build sheet from the museum.

It would seem to indicate the vehicle was in service for GM...possibly. The way they are applied looks like no particular care was taken, possibly another indication of GM use😁

The window sticker got here after a long delay. It was delivered to NAO Company Vehicle Operations (Willow Run), 2901 Tyler Rd, Ypsilanti MI. Probably a GM executive or manager?s car.
