I would be surprised if they don't go with the cheapest option, no matter what it is. I know the cops in NSW have been told to spend as much time on the side of the road as possible to reduce fuel costs due to the State's poor financial position.
They certainly will.....IF they can find something to replace the Falcoons and Commodes.
European stuff is too dear, and can't compete with the old Aussie performance, so for hwy patrol, the Stang looks likely. But they want/need a 4 door, so who knows ??
They also want a country wide "standard" car for everything, and NSW was the only state to have performance cars with upgraded brakes, so we might get downgraded to come in line with other states. Victoria are using poxy Camrys for hwy patrol ??
2018 will be the year to be a crook......you'll only need a souped up Toyota Camry to outrun them !!
