Well, if you're a criminal that's good luck. Ever tried outrunning a 5.7L V8 pursuit car? I think Monaros are (were) sold as Pontiac GTOs in the US, so imagine one of those with blue lights on being driven by a very determined cop...
Well, not only the galardo is a cop car, these things happen quite often, car manufacturers donate cars to police/firedepartment, in germany there is a porsche cayenne fire resque vehicle. I got a .pps file with all kinds of these cars in police uniform. (It's kinda about laughing with the belgian police cars, but now we've got more advanced stuff, although I've heard racing around brussels in that last car is a blast)
