A 1955 Mercedes-Benz 300SL Gullwing Coupe, chassis 198.040.5500548, completed at the factory on 27 July 1955 and finished in DB 608 Ivory over a red interior that survives intact to this day. Delivered new to Los Angeles — an uncommon destination for a Gullwing of the period — the car passed through very few long-term owners, including noted 300SL specialist Paul Russell and racing driver Lothar Motschenbacher, before entering a prominent Nevada collection. The matching-numbers engine appears undisturbed, and factory tags, trim, and brightwork are largely original and unmodified.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
