<VV> 7os Corvair article?

[Craig Pursley]

I'm trying to track down an article I read in a magazine in the mid to late 70s. It would have been a "Popular Mechanics" or similar type magazine. The article was mentioned on the cover and had to do with Corvairs suddenly becoming "cult classic" cars. 
Anyone a crazy enough Corvair nut to know this one?
I need the magazine name, date and title of the article for a story I want to reference.
Thanks
Craig
