Known issues by generation
The Iso Grifo, with its hybrid Italian-American construction, has specific vulnerabilities that collectors should be aware of. Common issues include rust and corrosion, particularly in the rocker panels and floors due to the Bertone steel-monocoque body design. Moreover, the Chevrolet V8 engines must be verified for matching-numbers status through careful block-stamping and casting-number cross-reference to avoid severe penalties at concours events. Ensuring proper documentation and historical records from the Bresso Iso factory is crucial for maintaining provenance, especially for high-value units that require Bizzarrini-engineered chassis pedigree verification.
