The Mercedes-Benz 300 SL Gullwing, chassis 198.040.5500272, is among the most celebrated production sports cars of its era, combining a fuel-injected 3.0-litre straight-six with a lightweight tubular-steel spaceframe and the iconic upward-opening doors demanded by that structure. Originally delivered through Max Hoffman's New York dealership in white over red leather, the car passed through notable American and Italian collectors before participating in the Mille Miglia Storica twice in the 1990s.
