My friend's Ferrari 360 F1 had failure of the F1 actuator.
The part cost was.....wait for it.....£15,000.
He complained to Maranello (UK distributor) but the reply from Ferrari was basically that the system was a copy of their F1 race car transmission, and in that car the part cost £150,000. So they considered that the price of £15,000 was "reasonable"
