Known issues by generation
While the Iso Grifo represents a pinnacle of Italian-American hybrid design, potential donors should be aware of specific model-related issues. For the Series I and 7-Litre models, the unique Bertone body construction may present rust and corrosion challenges, particularly in rocker panels, floors, and spare tire wells. Additionally, the verification of the Chevrolet small-block or big-block V8 engines through block stamping and casting-number cross-referencing is essential to ensure authenticity. The Series II may also face the same concerns, along with the critical need for documentation of the engine's provenance, given the late-production transition to the Ford Cleveland 351C. Each donor must recognize these nuances to maintain the vehicle's concours-grade status.
Donation value by condition + generation
In today's market, the value of a concours-grade matching-numbers Iso Grifo can range significantly. Auction houses like RM Sotheby’s and Gooding & Company have seen Series I models valued between $300k to $600k+, while the rare 7-Litre IR can fetch $800k to $1.5M+. The Series II models, particularly with concealed headlights, typically range from $400k to $700k+, and the Targa models often command $700k to $1M+. Certification through Bizzarrini records and verification of original components, such as Borrani wire wheels and period-correct trim, significantly enhance value, while factory color changes are a severe red flag at this tier. A qualified appraisal is crucial to ensure the accurate representation of your vehicle's value.

Donating your Iso Grifo involves a streamlined yet thorough process. A qualified appraisal is mandatory to support the donation, with IRS Form 8283 Section B required for any donation exceeding $5,000.
