The Maserati A6G/54 is the definitive post-war A6 series grand tourer, introduced at the 1954 Paris Auto Show with only 60 examples produced, of which just 21 received Allemano coachwork. Chassis 2175, completed in August 1956 and delivered new to a Roman customer, later had its engine removed by an American enthusiast before being acquired by its current owner and returned to Italy circa 1989. A full restoration was undertaken, and in 2008 the car was reunited with its correct matching-numbers inline-six engine through the research of Maserati historian Walter Bäumer.

Maintenance & restoration

  1. 2008

    The car's original matching-numbers inline-six engine was located and reinstalled, reuniting chassis 2175 with its correct powerplant; the correct cream exterior and black interior with cream detailing were also confirmed as present.

    Achieved with the assistance of Maserati historian Walter Bäumer, whose research identified and authenticated the original engine.

  2. Restoration

    A comprehensive restoration was undertaken after the car returned to Italy, during which it was fitted with the engine from chassis 2186 as a temporary unit pending recovery of its correct motor.

    Commissioned by the consigning owner following acquisition around 1989.

  3. Modification

    The original twin-cam inline-six engine was removed from chassis 2175 and transplanted into the Zagato-bodied sister car, chassis 2186; 2175 was sold as a rolling shell without a powerplant.

    Work carried out during Joe Alphabet's ownership in Los Angeles, circa late 1980s.
