Due to low demand, only 52 units of the Alfa Romeo G1 were ever built, and this 1921 G1 is believed to be the only running G1 left, making it a highly exclusive vehicle. Thus, this 1921 Alfa Romeo G1 has an estimated value of $1.5 million USD, which isn’t far off from the Ferrari Daytona Alloy barn find that sold for $2.1 million USD back in September.
The G1 is a very significant piece of Alfa Romeo’s history, as it was the first vehicle to wear the automaker’s badge after it was founded in 1921, which is when ALFA (Anonima Lombarda Fabbrica Automobili) partnered with Italian engineer and entrepreneur Nicola Romeo.
The G1 featured a 6.3-liter straight-six under the hood – the automaker’s first six-cylinder – which was good for 70 horsepower. This particular G1 was used as a farm vehicle before sitting in storage until 1965. The G1 has since seen two restorations, and has showed face at Pebble Beach Concours, the Mille Miglia and the Goodwood Member’s Meeting.
RM Sotheby’s will auction off this G1 at its Arizona event in January, and if it really is the only running G1 left on the planet, then we think it may sell for more than the projected $1.5 million. Do you agree? Give us your best guess in the comment section below.
