Plenty of car companies have been known to buy back some of their historic models in order to preserve their history and display them in their museums. When Toyota tried to find their first car (the Toyota AA) they found there was none left possibly due to Japan’s love of crushing outdated cars for the latest model and the fact that only 1400 were build from 1936 till 1943. The next plan was to create a replica of the car but as a full set of plans were not available the replica was built from what plans could be found from over the models lifetime. Today the replica that was built for Toyota’s 50th anniversary sits in Toyota’s automobile museum in Nagoya Japan. While the car may not be exactly like the one you could buy in the late 30’s to early 40’s it is pretty darn close to what the real thing would have looked like if there was still one around.
