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.
