Jaaaaag police cars look good, unless they are in your rear view mirror

In this area; if they wanted to be undercover they`d need a Corsa, on ridiculously-wide alloys, lowered `till the sparks fly off the balljoints, an inconsiderately-loud exhaust and be driven maniacally; without tax or insurance.

That's a truly nasty trick to play on poor unsuspecting motorists. Next thing you know there'll be coppers walking the streets or going round on bikes.
