Summary Verdict

The 2002 Ferrari 456 M GT is a capable grand tourer with a generally solid mechanical foundation, particularly its V12 engine. However, like many high-performance exotics of its era, it requires diligent maintenance and can be susceptible to specific issues. The most common concerns revolve around the timing belt service, cooling system integrity, and potential wear on the clutch and F1 transmission components. Electrical gremlins, often related to the BCM or aging alternators, can also arise. While the suspension and exterior/interior are relatively robust, specialized knowledge and significant financial resources are necessary for repairs, especially for the F1 transmission and adaptive suspension systems. Regular servicing by marque specialists is paramount to ensuring long-term reliability and enjoyment.
