The right-rear photo of the car in the 1982 book matches the right-rear photo in the 1968 Speed and Supercar "Mindbender" article. The 1982 issue also had a story written by Joe Oldham, a member of the Cars Magazine staff in the late '60s/early '70s, telling of his '69 B-M Camaro. My take on it is that the guys writing the 1982 special edition, including Oldham, culled the circa '68-'69 Motion Camaro photos from the Cars archives to use as filler for the '82 Camaro special issue. The '68 car with the NY "ML 8907" plates was, as far as I can tell, Joel Rosen's personal car and his demonstrator, as evidenced by several 1968-69 articles on the car. Benny Benzino may well have had a '68 B-M Camaro but I don't think it's the "ML 8907" car seen in the photos in the '82 magazine special. I think the 1982 article's writer (not named in the article) or perhaps the editors took a little artistic license in putting those photos with the story of Benny's Camaro. But that's just my opinion, based on researching magazine articles from the '60s, and I could be wrong. Great stories though!
