i would have thought as its one of the advertising cars for the riopresige then it will be one of the cars they have in thier fleet, according to their website that would make it the Gallardo Spyder.
The pic was taken in 2005 though so their fleet may well have changed. It's funny because this point did come up in our discussion of it as well! The spyder is though I think a cabriolet model?
I'd say the headlights alone are enough to identify it but neither of us are quite sure what it is.
