Wow, that was a lot of work!
Two of the promotions stood out. The NFL promo, which showed the winner with the car and it had an M-plate (manufacturer plate), 13M942!
And the Estes visit to Cinci. Quite the promotion! I assume the 250 cars were 250 local orders - I imagine that got complicated and thus dropped.
I know we've run across a few of these cars over the years. I recall a Sears giveaway 67 pacer that wasn't a pacer.
