Thank you for your interest our spot titled "1975". Unfortunately we will not be able to release this spot to you, as we do not have the rights to air the spot on the internet other than for our own advertising purposes.
Even if we did have the rights, there are actors in the spot who would need to be paid additional talent and residual costs.

I have just been pouring over the February 1987 issue of Collectible Automobile Magazine, one of the few out there which is scrupulously fair to all marques. There is an excellent article on pages 22-48 by Chris Halla on the 1960-69 CHEVROLET Corvair (caps mine).

Absolutely no mention in the very thorough article at all about it being a "companion marque" to Chevrolet (the recent Geo probably comes closer to filling that role), in the same way that Pontiac was to Oakland, Viking was to Oldsmobile, and LaSalle was to Cadillac; all of which never bore their respective parents' marques on the exterior (or if they did, it was very subdued).

There are Bowties splashed all over every Corvair ever made. And I am sure they were titled as Chevrolets, not Corvairs. Pages 45 thru 48 show that GM was contemplating making Buick, Olds and Pontiac versions, the Olds to revive the "Sixty-Six" designation and the Pontiac, the most developed of the three, to be called "Polaris."

I hope this serves to put to rest the idea that the Corvair is an orphan.

As for your post about the Corvair, consider that early in that car's life, GM did market it as a separate marque under Chevrolet's domain, kinda like the companion cars that were all the craze in the late 20s, early 30s. By the mid-60s, it became commonplace for marques to offer several different lines, thus the Corvair became a Chevrolet wholesale. Not sure whether to call it an orphan still, but that thar's some sort of explanation.
