Not sure if this was an internal concept or vision of things to come. We did read that the Mustang GT would offer new 18-inch rims for 2006. Are these it? It's not a GT in the pic (if the badging is correct) and these don't look like 18's. This 'Stang also has color keyed outside mirrors and clear turn signals. This was in the background of a photo of Larry Erickson, Mustang Chief Designer. Can anyone shed more light on this pony?
