Engine
4.0L inline-six twin-cam with Lucas mechanical fuel injection
Colour
Dark blue metallic

A 1966 Maserati Mistral 4000 Coupé with coachwork by Carrozzeria Frua, chassis AM109/A1 724, representing one of only 454 examples built with the top-specification 4.0-litre twin-cam six-cylinder engine. Delivered new to Verona in May 1966 in silver with blue leather, it passed through a German owner before reaching its current custodian in 1982. The aluminium body was repainted dark blue by a prior owner, while the original light blue interior survives. A comprehensive restoration was carried out in the 1990s, and the matching-numbers engine has since been overhauled.

Maintenance & restoration

  1. Modification

    Exterior colour changed from original Argento Auteuil silver to dark blue metallic by a prior owner.

    Carried out during Hans Haemer's ownership, prior to 1982.

  2. Restoration

    Complete restoration of the vehicle undertaken during the 1990s. Paintwork now shows minor age-related wear consistent with the work being some decades old.

    Commissioned by the current vendor.

  3. Engine rebuild

    Full overhaul of the original matching-numbers engine, including fitting of new injectors to the Lucas mechanical fuel injection system. The fuel pump and injection pump were not part of this overhaul.

    Described as recent at time of cataloguing; the injection system is reported to function well.

  4. Modification

    Adjustable shock absorbers installed to improve ride quality, replacing the original dampers.

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.
