Otto, you are right and masterful about the Oros/Engel design. I you have more about that "Quicksilver" concept I'd like to see. I kinda collect all Ford concepts and never heard of that except a 1983 Ghia project.
I had forgotten you had felt "a Ford vibe" before. That greenhouse has been used on the 1960 Fairlane 500, and on the 1960 Edsel (Ford bodied but made by the Mercury Edsel Lincoln division). But I have found this picture, among others, labeled "1960, Mercury, styling" and can't find where anymore.
Even if by luck, Ultra gave the right make, unless my source is proven wrong.
If so, I'll have to substract his point! I hope I won't be banned after that.
