FXX (Enzo-based programme) · 2005–2006
- Distinguishing features
- Track-only Enzo derivative with 800 hp 6.3 V12, sequential gearbox, slick tyres and full data acquisition. Owners run cars under Ferrari's Corse Clienti programme; cars are not road-registered.
- Value premium
- Standalone market — multi-million; not directly comparable to a road Enzo.
- Inspection points
- Verify the chassis is one of the 30 originals or 8 Evoluzione upgrades through the Corse Clienti register. Confirm the car's recent run-hours and refurbishments.
