How much of the enzo ferrari is made of carbon fibre??

All the steel frame (chassis) is made of carbon fiber, so more than half of the car, the top of the "motor" also , the interior of the door, and all the aerodynamic appendices. Conclusion don't crash it or it will cost a lot of money! ;-)

Thanks a lot. :-)

What about the base of the car and the rear diffuser??

hahaha steel frame??? anyway the chassis is made from 100% carbon fibre with carbon panels and carbon doors. the only parts that are not made from carbon are the engine, suspension and wheels, there is also an aluminium honeycomb section to the floor pan. there is no steel.
