Who is going to race a multi-million car in anger? I suspect we haven't seen many real Ferrari 250GTO on the track for years. If you own such a jewel the money for an exact copy (perhaps £200K) is well spent if you want to go racing - and who could blame you?
I'm guessing only, but when a car reaches that value, most of the cost is in the provenance; what it is and what it was.
As such to crash a £25m car (using Nick Mason example above - who was on the Morgan stand in Geneva BTW) won't cost anything like that to repair, even if you had to fabricate new parts.
