The 1954 Arnolt-Bristol Bolide Deluxe Roadster, chassis 3105, is one of only 142 examples built through a collaboration between Chicago industrialist Stanley 'Wacky' Arnolt, Carrozzeria Bertone, and Bristol Cars, featuring coachwork styled by Franco Scaglione over Bristol's BMW-derived 2.0-litre six-cylinder chassis. This late-production Bolide Deluxe was reportedly gifted new to Playboy founder Hugh Hefner, subsequently changed hands several times, and has been in long-term ownership in Belgium since 1994. Matching chassis and engine numbers are retained, and the car is eligible for the Mille Miglia.
