A one-off coachbuilt Alfa Romeo 1900C SS built by Mario Boano for the 1955 Turin Motor Show, its flowing yellow-and-black bodywork was inspired by a coupe Boano had created for Argentine president Juan Perón. Fitted with a competition Tipo 1308 engine and twin Weber carburetors, the car passed through several Italian owners before entering a prominent Bolognese collection. Brought to the United States in 2014, it was shown at Pebble Beach in the Preservation Class in 2015, then restored to its original Turin livery by Fastcars Ltd., winning Best in Class at Pebble Beach in 2017.

Maintenance & restoration

  1. Bodywork

    At some undated point the car received a repaint in red over its original yellow-and-black livery; this was the only significant departure from original condition noted prior to the subsequent restoration.

    The original paint was discovered beneath the red finish and used as a colour reference for the later restoration.

  2. Mechanical

    Correct spark plugs, ignition wires, and contact-breaker points were sourced and fitted to return the ignition system to proper specification.

    Carried out during the period of pre-Pebble Beach preparation; other original mechanical components including the engine, induction system, tubular header, and dual-outlet exhaust were confirmed to be intact and unmodified.

  3. Restoration
    Fastcars Ltd.

    Full restoration to the car's original 1955 Turin show specification, including a bare-paint strip that revealed a sound, uncompromised body, followed by refinishing in the correct two-tone yellow-and-black scheme using the original paint as a colour reference. The original black leather interior, instrumentation, Nardi steering wheel, and Autovox radio were retained. Work is documented with photographs and receipts.

    Commissioned by the European collector owner; workshop located in Redondo Beach, California. Completed before the 2017 Pebble Beach Concours.
