Colour
Green over light green

Bugatti Type 57 chassis 57644 is one of only eight examples bodied by Letourneur et Marchand to coachwork design 5877, a four-seat three-position cabriolet with pontoon front fenders and semi-recessed headlamps. Delivered new in late 1938 and retaining its numbers-matching engine and coachwork, the car spent 66 years in the care of one Dutch family before passing to its current owner, who commissioned a thorough restoration including an engine rebuild and period-correct supercharger upgrade, raising performance to Type 57C specification. The car appeared at the 2018 Pebble Beach Concours d'Elegance, where it earned a class award.
