The 1956 Mercedes-Benz 300SL Gullwing Coupe (chassis 6500176) was delivered new to Los Gatos, California in July 1956, finished originally in white over red leather. A US-market example with continuous West Coast and Nevada provenance, it subsequently entered the prominent Mann Collection in New Jersey before returning westward. The car received a high-quality restoration by noted 300SL specialist Hjeltness Restorations, which refinished it in silver, refurbished the red leather interior, fitted an air conditioning system with auxiliary cooling fans, and sourced a period-correct 300SL Roadster replacement engine. It has since been actively used on touring events.

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.
