A 1957-build North American-specification Mercedes-Benz 300 SL Roadster, one of 554 completed in the model's first production year. Delivered to the United States in November 1958 finished in Graphite Grey over Cream leather, it spent its early decades on the California coast before passing to a European collection in 1986. The matching-numbers body, chassis, and 3-litre straight-six engine survive intact, though the front chassis crossmember appears to have been replaced at an undetermined point. The interior has since been retrimmed in dark green leather.
