Correct, an Audi NSU. I think Chris's NK was 2nd or 3rd.
Thank you Sven.
I can read the NSU etc. but did not know it was part of the Audi family.
Never seen or heard of this car.
When I was on top of a mountain in Colorado this summer in my coupe a guy came up to me and told me this story about how BMW stole lines from the Corvair. I bit my tongue and assured him that was not the case.
He said he read it in a magazine.
Maybe this car is what he was thinking about and got the manufacturers mixed up? He was a Corvair enthusiast of course and owned a couple.
