Light yellow

One of only 56 examples built, this 1974 Porsche 911 Carrera RS 3.0 is a street-specification homologation special invoiced in April 1974 and originally delivered in Light Yellow over black leatherette. Unusually, it retains factory-spec presentation without Carrera RS side graphics and is fitted with a steel electric sliding roof. It passed through several documented German, British, and Swiss owners before its current custodian acquired it in 2004, and retains original RS 3.0 features including a period roll cage, 917-derived brakes, and chassis reinforcements.

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.
