What's the coolest/quirkiest undercover cop car you've ever seen?

The cops in my hometown have an undercover WRX STI, which was apparently confiscated from a drug dealer!

Seen plenty of marked STI/Evo cars. Not unmarked! Amongst the plethora of BMW/Volvo/Skoda unmarked cars in the UK, I’ve seen a Focus ST and a Mk5 Golf R32 that was damn cool.

I wish my drug dealler had an STI.. .. sounds so wrong but it would be nice

in spain we have daily looking cars that have a speed camera on top with a camouflage like this
its a very assholeish movement

Lifted Toyota Tacoma. And a grandma beige Toyota Camry. But they are used by state troopers who only really use it for traffic violations
