I have a large mock up made by the advertizing firm that handled the Camaro introduction. Interestingly there are differances between what was rendered in this and what came out in the production cars. Most notably the mock up nose apears about 3 inches longer (more like a Jag), and the turn signals on the standard grill which are in the valance the same as an RS. The round grill lights are rendered as driving lights like a Mustang GT. I wondered if anyone else has come across this preproduction light idea?
There are other changes (fender eyebrows, mirrors, striping, vett spinner hubcaps, etc.) made to the ad before it apeared in Life magazine. Also copy was added that in the mock up show as squiggly lines.
