Ferrari Enzo — spec data and generation history.

Halo of its era and direct successor to the F50 — F140 6.0 V12 NA (650 bhp), carbon-fibre tub, F1-derived gearbox, 400 cars built (plus 1 extra gifted to Pope John Paul II for charity auction). Pininfarina styling led by Ken Okuyama; carbon-ceramic brakes standard from the factory (a road-car first at this scale). Donor car for the FXX track programme and the Maserati MC12. Untouchable values now — every road-registered example has appreciated relentlessly.
