1921 Alfa Romeo G1 $1 million plus

“The 1921 Alfa Romeo G1 is incredibly desirable for its historical value alone,” says Gord Duff, global head of auctions for RM Sotheby’s. “It is an early example of the very first Alfa Romeo model ever produced, a car that has never before been offered at auction, and—given this is the only running example in existence—one that may very well never be offered publicly again.” According to Duff, the 6-cylinder G1 was designed to compete with its American and British luxury contemporaries. However, due to high fuel costs and road taxes at the time, only 52, including two prototypes, were ever built. The G1 (chassis 6018) hits the block during a 2-day sale in Phoenix on January 18 and 19. It is expected to race past $1 million. rmsothebys.com
