83411roadGermany
Engine
1.6L inline-four, Porsche 912-based, built by Canepa
Colour
Black over red leather

Chassis 83411 is a 1957 Porsche 356 Speedster originally completed on 31 May 1957, factory-specified in red over beige vinyl and destined for the US market via Max Hoffman's New York dealership. Equipped with a 1600 Normal engine and US-specification fittings, its early history is unrecorded. The car later received a comprehensive restoration, emerging in black over red leather with a factory hardtop and Nardi steering wheel; a Porsche 912-based engine built by Canepa replaces the original unit, which is retained with the car.

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.
