I had a 71 Datsun 510 sedan. Bought it new (and traded in a 68 Karman Ghia convertible) to carry the new baby around.
Fun car to drive, but terrible in the winter. The thing rusted before my eyes!
I got rid of it three years later after a dump truck ran over the front corner breaking off a wheel on my construction site.
I never bought another Nissan until 2003 when I bought a G35.
