Black over tan

Chassis 89753 is a 1961 Porsche 356 B T-6 roadster completed by D'Ieteren, the Belgian distributor, on 28 December 1961 — one of just 248 such cars distinguished by their twin engine-lid ventilation grilles. Originally delivered in Oslo Blue over grey leather with a 1600 S engine and reclining seats, the car spent the majority of its life in California and underwent a cosmetic refurbishment in the mid-2000s, emerging in a black-over-tan colour scheme. The original 1600 S engine is retained.

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.
