Do you agree we have already beaten the Buick vertical grille to death? Front comparison not as dramatic as the rear. Looks like Chevy used the tailings or off-cuts from the Buick grille stamping. Imagine the poor guys on the Buick assembly line installing 200 of those little squares - would need about 50 guys in 25 work stations !!! Process or industrial engineering to co-ordinate mounting 4 squares per worker.
