Another: 1933 Dymaxion. Built by Buckminster FUller, the same guy that designed the American Pavillion at Expo 67, i.e., the big Ball on Ste-Helene Island.
The 67 X (also Toronado 67X, Esso 67X, Toronado 70-X or 70 X) is a Canadian-built automobile, based on the Toronado, that was designed and manufactured by automobile customizer George Barris for Canada's Expo 67, where they were raffled off in a contest sponsored by Esso. Only four of these vehicles were ever made but they included swiveling seats, a sofa, and even a refrigeration unit, with an overall sleek-looking design. Commercials for this vehicle were aired in the Stanley Cup Playoffs final game between the Montreal Canadiens and Toronto Maple Leafs.[11]
