Colour
Black

Chassis 350 is one of only four Iso Grifo Series II models built with open Targa coachwork, making it among the rarest examples of an already scarce Italian grand tourer. Constructed on 4 July 1971, it combines the Series II's refined styling — including retractable headlamps — with a 300-horsepower 5.7-litre Chevrolet V-8 and five-speed ZF gearbox. First delivered through a Koblenz dealership to an owner in Aachen, the car has spent its most recent quarter-century in a single private collection and is presented in black with white leather interior on Campagnolo magnesium wheels.

Are you the owner of this 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.
