Chassis 7500594 is an early Mercedes-Benz 300 SL Roadster, approximately the 518th of 1,858 built, finished from new in ivory over red leather — a combination it retains today. Likely delivered new to the United States, given its American-specification headlamp lenses, the car passed through American ownership in the 1980s before being acquired by a Portuguese enthusiast in 1996. It retains its original engine, bodywork, and steering box, and carries a FIVA identity card issued in 2007.

Maintenance & restoration

  1. 2007
    Inspection

    The car was assessed and issued a FIVA identity card, confirming its eligibility for major historic-vehicle events.

  2. Restoration

    A comprehensive restoration was carried out at some earlier point in the car's history; the work is described as well-preserved and of older date, with the original ivory-over-red colour scheme maintained throughout.

    Exact date and workshop unknown; the restoration predates the current ownership period.

  3. Service
    Mercedes-Benz Classic of Portugal

    Following acquisition in late 1996, the current owner had Mercedes-Benz Classic of Portugal carry out selective remedial work to bring the car up to a satisfactory standard without altering its character.

    Scope limited to what was needed; described as a sympathetic freshening rather than a full restoration.

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.
