if this car resides in Argentina it must be Horacio's himself Don't you think? http://exoticspotter.com/list.php?page=6&batch=bt0001/bt0001_277300.jpg&model=all&make=all&location=all&frm=batch_listing
Horacio Pagani now drives a Zonda F with italian plates DA 307 CD, same colour combo of that one. But since this Zonda S has been spotted in Argentina, who knows...
This car has also been spotted in Monaco and London. The only fact is that the owner likes to take it with him as he travels.
Indeed .... Punta del Este, Uruguay I bet you can pick up the best looking girls in Punta with this car !
