198.040.5500243roadGermany
Engine
3.0L inline-six with mechanical fuel injection
Colour
Dunkelgrau (dark grey)

A 1955 Mercedes-Benz 300 SL Gullwing coupe, chassis 5500243, distinguished by its exceptionally rare Dunkelgrau (Dark Grey) factory finish paired with a red plaid cloth and fawn vinyl interior — recorded as the only example so configured in Eric Le Moine's authoritative Gullwing register. Completed in April 1955 to US specification, the car passed through a series of dedicated American enthusiasts before undergoing a comprehensive ground-up restoration by a team of California-based specialists using parts sourced directly from the Mercedes-Benz Classic Center.

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.
