Engine
2.0L 70-degree V8, five-speed gearbox
Colour
Carrera Panamericana racing livery (restored)

Chassis BS 503 is the third Siata 208S Spider built and the first bodied in production-specification aluminium alloy, delivered to Hollywood sports-car dealer and racer Ernie McAfee in 1953. McAfee used it as both demonstrator and competition car, entering it famously in the 1953 Carrera Panamericana before it became known as the 'Holey Terror' for its extensively drilled lightweight bodywork. After decades of separation, the original drivetrain and Motto coachwork were reunited and subjected to a comprehensive Italian restoration completed in 2014, culminating in an appearance at the 2022 Pebble Beach Concours d'Elegance.

    Modification

    McAfee transformed the car into a dedicated lightweight competition machine, drilling and perforating numerous non-structural components to reduce mass and cutting cooling vents into the rear wings. A secondary fuel tank with an anti-roll bar was also fitted for the long Carrera stages.

    Work carried out over approximately two months in preparation for the 1953 Carrera Panamericana.

    A comprehensive, historically authentic restoration was undertaken: Quality Cars of Italy fabricated a correct replacement chassis and repaired and refinished the coachwork, while Roberto Di Checchi of Motor Holding performed a full mechanical and engine rebuild. The finished result replicates the car's 1953 Carrera Panamericana specification, including correct livery, period stickers, secondary fuel tank, anti-roll bar, and cowl-mounted footwell vent.

    Commissioned by the European collector who purchased the components in 2007. Extensive reference was made to period photographs of the car at events including the 1953 Carrera Panamericana.

    Original Siata engine replaced with a Buick V-8 unit and the car was repainted in metallic green, consistent with prevalent American racing practice of the period.

    Esteemed Italian car historian John De Boer reunited the original drivetrain components with the Motto coachwork after acquiring both separately in the mid-2000s.
