The 1974 Porsche 911 Carrera RS 3.0 (chassis 4609106) is one of only 55 examples produced as a homologation special intended to underpin the factory-raced 3.0 RSR. Uniquely, this particular car served as an official Porsche factory demonstration vehicle (Vorführwagen), confirmed by former Porsche test driver Jürgen Barth and documented in John Starkey's authoritative reference work. After export to the United States in July 1974, the car passed through a small number of well-documented owners across three countries, retaining its original white paintwork, Carrera RS script, engine, and gearbox.

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.
