I'm assuming from the film footage I have of the parade that the "Festival" cars got the gold madallion on the rear quarter panel (8 or 10 inch sticker)and the others "commitee"did not..The GM Canada paperwork is very interesting..Why were the cars sent to "GM show car account" Is that why they were built? Maybe for this racetrack that there is a picture of? If so were they all sold as used? Still remaining to be seen is the exact meaning of "Special paint" Blue stripe? Clear coat? or special instruction on a broader scale? The Gm paperwork Says right on it 'RS'..Why has it been so long for this to become common knowledge?Maybe checking your sources when you write a book (or magazine article)doesn't include the car world
