1930 Alfa Romeo 6C 1750 Gran Sport Spider (4th series, Zagato-bodied, short wheelbase)
- Engine
- 1.75L supercharged inline-six
Chassis 6C 8513064 is one of approximately 102 fourth-series Alfa Romeo 6C 1750 Gran Sport spiders built, bodied by Zagato on the short wheelbase. A type celebrated for its domination of pre-war under-2-litre racing, this example passed through several notable American hands from the late 1960s onward, including venture capitalist Thomas Perkins and Colorado marque collector Jackson Brooks, under whose stewardship Phil Hill drove it to fourth overall at the 1985 Monterey Historic Races. The car retains its matching-numbers engine, confirmed by a 2023 Jim Stokes Workshop inspection, and has completed the Mille Miglia Storica on four occasions.
