I had just heard a few weeks ago that one of the Cougar II's was kept by the Detroit Historical Society museum, and I was thinking about trying to find it to take a look. I was taken totally by surprise to see it downstairs at the Autorama. It was almost hidden at the very back, one of the last cars I saw. It would have been very easy to miss.
I wish I had taken some better pictures, but I was tired, and the group I was with was definitely ready to go after 6 hours of walking around looking at cars.
