See some good stuff. Newest car[s] seem to be 1965 models, so I guess that pins it at that time approximately. Oops...hold it; just looked again and THINK I see a 66 Oldsmobile over on the left. Anyway, 3 65 chevies, a 62 Pontiac, 60 Chrysler, an early Mustang, a Mercedes, a 58[?] mopar product, a VW, a 56 Ford, a 58 Ford, two 61 model wagons - a Ford and a Chevrolet - a couple of buicks... lots of fun stuff.
