I have this saved as a Martini-Mini, which would be a repost. So perhaps Martini-NSU?
Actually that's not at all what I have it as!
My info is not necessarily any more correct than yours though; would you PM me with some proof/a site that I can check out against my own info?
If my puzzle pic is indeed the Mini-Cooper Martini (and I agree it does look awfully similar) then it would be a repost and would need to be merged.
