These cars would definitely be a very nice car collection for someone, but they're "just" patrol cars if you're from Dubai. :-)

pretty cool. but would it be more effective to use a chopper and a few crown vics or chargers?

I think they're going for the "flash" more than practical application. Besides as long as oil prices are up, they can buy what they want.

they definitely have the 'flash' portion covered. :D

Very tempting to get arrested just for a ride in a Veyron or an Aventador! LOL
