At first this Ferrari appears to be just a stretched-out 512 TR with a 355 rear-end, but in fact it is a the only working prototype of the Ferrari Enzo which has now become available for sale. The Prototipo Enzo chassis number M3 is powered by a race-bred V12 engine which puts out 680 hp, considerably more than the actual production car.
Apart from that classic body and interior, this car has modern underpinnings which have been used to make the Enzo and the 599. So this is a very special car, the Enzo’s mother! The price has not been mentioned yet, but this being a one-off certified prototype Ferrari, you may rest assured it’ll a six figure digit.
