9309800848roadGermany
Engine
3.3L air-cooled flat-six, single turbocharger, Bosch K-Jetronic fuel injection, 265 bhp
Colour
Silver with black anodized trim

A 1979 Porsche 911 Turbo (Type 930) finished in Silver with a black leather interior, this U.S.-specification example is the 848th of 1,200 built for the model year. Exceptionally rare in its state of preservation, it had covered just 548 miles at the time of cataloguing — the result of early dry storage after delivery through a Philadelphia dealership. Retaining original tires, documentation, and tools, it represents a virtually unused survivor of Porsche's flagship model of the era.

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.
