Four messages in a row. I've got a renaming issue to deal with. Two of these station wagons at another Minnesota antique car meetup are 1963 Oldsmobile Dynamic 88 Fiesta station wagons. The third on the right might be a 1963, but I have my doubts.

I looked up the grille for that blue one on the Old Car Brochures website, and I didn't find anything resembling it.
