Aston Martin CC100 Speedster HUGE revs and sound!
 

I have filmed the one off car made by Aston Martin in order to celebrate its centenary, called Aston Martin CC100 Speedster Concept powered by a 6.0 liter V12 engine during the 2013 Concorso d'Eleganza Villa d'Este.
Video shows some exterior/interior shots of the car, then you can hear it starting up and revving hard!!
