The 1958 Mercedes-Benz 300 SL Roadster, chassis 241, left the factory finished in White Grey over red leather and was delivered new to its first owner in Lucerne, Switzerland on 19 July 1958 following factory collection. Retaining its original service book, factory data card, and all numbers-matching components throughout a carefully documented ownership history, the car underwent a comprehensive restoration commencing in 1990 and has received multiple professional refurbishments since, remaining in notably original and well-preserved condition.
