I would post a picture of it, but I can't yet. If you go to the pontiac site and look at the pictures. Check out the one on the top row 7th from the left. It is the same one that people have been checking out to look at the darker two tone color option. Behind the head rest on the silver portion just infront of the rear deck lid is a square door looking thing that seems to pop off. If you look at pictures for the sky it is on the drivers side. Does anyone know what this is? Is it just an access panel?
