1964 Maserati Mistral Spyder

Engine
4.0L inline-six (Tipo 109), triple Weber carburetors, five-speed manual
Colour
Black

A 1960s Maserati Mistral Spyder, chassis 665, finished entirely in black with matching convertible and factory hardtop. Among the rarest variants of the Mistral line, it is one of just 37 open-top examples built with the 4.0-litre Tipo 109 straight-six — an engine lineage tracing back to 1950s racing machinery. The original engine has been exchanged for a correct-type 4.0-litre unit from a Mistral coupé, fitted with triple Weber carburettors. The beige leather interior retains period instrumentation and optional factory air-conditioning.

    The original 4.0-litre engine was removed and replaced with a correct-specification 4.0-litre Tipo 109 unit sourced from a Mistral coupé, equipped with triple Weber carburettors.

    The replacement unit is described as a correct-type substitution, though not the matching original engine.

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.
