If they did, I've never seen one. The promo models were generally the car with plenty of new features or design, and for 64, the Cutlass was the one. Then in 65 they went back to the full-size 88 coupe, and 66-70 were Toronados.
Also depended on who made the promos for the car company. JoHan would make the more obscure body styles such as station wagons (which were a high-profit vehicle then same as an SUV is now) where AMT would go more for hardtops.
Then we all benefited from the annual model kit production!

I even remember 1:24 scale polyethylene toy cars based on some of the JoHan tooling. I bet I put 100,000 miles on some of those in my sandpile. I had a bigass sandpile out under the oak trees in the side yard, and me and my cousins would have roads, neighborhoods, ponds, construction sites, you name it, we imagined it and built it with wood scraps and the like.
