i was looking around for pictures of some old Nissan/Datsun cars and i stumbled upon this website. it has pretty much a complete history of the roots of Nissan (up 'til '82) and has a timeline with pictures of almost every car model from each different time period spanning from 1911 to 1982! i just thought it was great to look at some of the old concept cars that nissan had from long long ago. its very informational and fun to look at, i would recommend reading through it if you consider yourself a nissan/datsun enthusiast.
