Once this shell is cracked or damaged, that piece of CF basically looses its strength. It can be repaired, but it is extremely expensive, and apart from changing the entire part, the part will never be as strong as it originally was. Given that the chassis of the Carrera GT is probably damaged in the above car, that Carrera GT is ruined. Even if it was repaired, it'll never be as good as it was before.

Though my guess is that the car is a write-off.
