UPDATE:

There was a passenger in the car and he came forward... Name not released yet... Driver still not identified or found...

I find this fascinating in a sick sort of way...

Here's the only list I could find of ENZO owners...
Bernd Pischetsrieder, former chairman of BMW and current chairman of the Volkswagen Group
Eric Clapton, Member of Cream and acclaimed solo artist - took deliver of very first Enzo to be shipped to the UK
Frits Kroymans, Ferrari-importer for The Netherlands
Jay Kay, Frontman of Jamiroquai
Nick Mason, Drummer of Pink Floyd
Frank Warren, Boxing Promoter - Car recently written off in collision with bus
Tommy Hilfiger, Clothing Designer
Pharrell Williams, Music Producer, Frontman of Rock/Rap group N.E.R.D
Michael Schumacher, Formula 1 driver for Scuderia Ferrari.
Teemu Selänne, NHL player.
Aaron Kwok, one of the Four Heavenly Kings of Cantopop.
Steve Wynn, casino magnate
Roger Penske, motorsport legend, owns Ferrari dealership in partnership with Steve Wynn.
Lindsay Fox, Australian transport magnate, owner of the only Enzo with a yellow roof.
Pope John-Paul II, Late head of the Catholic church. Was presented with the Enzo as a gift for his 26th year of Papacy. The car was auctioned by Sotheby's for Charity to help victims of the Boxer Day Tsunami.
Donald W. Wallace, founder and chairman of the board Lazydays RV SuperCentre bought Enzo no. 400 at the Ferrari Auction in Maranello
Nicholas Cage.

I'm betting on it being one of the following cars... Nick Cage's, Pharrel Williams or Jay Kay's...
