Sure that wasn't '69? According to Wikipedia the 850 was produced between 1964 and 1973.
A friend of mine had an 850 sedan in the late 60's.
I graduated in 1960 so I guess it wasnt an 850. I know it was a really small car and 4 or 5 of us could lift the thing and push it around.
It did an 1/8th mile wheelie with bug power (never on the street).
It's currently gutted in preparation of putting the drive train of a 1st gen Eclipse turbo into it (about 300 ponies, mid engine, AWD: flipping the transfer case).
Kind of a redneck Atom.
For fun search youtube.com for 'smart car Hayabusa'.
I want one of those too.
