The oldest Toyota still on the road?

I remember seeing the Toyota 1900 or Tiara on display at our county fair back about 1960 or 1961. There was a Toyota dealer, but the dealership didn’t last very long. In 1971, I test drove a 3rd generation 1968 Toyota. The body fit together well and it was much more quiet than the 1971 Datsun P 510 demonstrator that we also tested. However, the 1968 Toyota had a 2 speed automatic and didn’t have very good acceleration, so I took a pass. The car was on the lot of the Chevrolet dealer, so I reasoned that the former owner may have been dissatisfied after 3 years of owning the car.
