RM Sotheby’s announced that will offer on sale an exceptional copy of Alfa Romeo in Phoenix, Arizona in January.
It is about Alfa G1 from 1921, the first production model of the Italian company, with this specimen believed to be the only one in the world that remained complete.
Alfa made just 52 pieces of the G1, and it is powered by the first six-cylinder engine of this manufacturer (6.3-liter with 70 hp), which in 1921 made it a supercar!
