I just had a question similar to this on another GP forum because my bumper is a solid color and doesnt sat pontiac either. I guess that from the factory all cars came with the grey valance and said Pontiac except for 2002 40th anniversary cars and 2003 Limited edition. Also 2003 didn't have paint on the valance i guess. It was just left alone from my understanding. Then cars like mine that don't say pontiac are an aftermarket because they couldnt say pontiac for copyright reasons.
