History
An Australian-delivered 1921 G1 roadster was confirmed by the Alfa Romeo museum as the oldest Alfa Romeo in existence and the sole survivor of 52 built. It was one of seven G1s imported to Australia and sold new for 850 pounds to a Queensland station owner. It was rescued by enthusiasts in 1964.
