The local plod back in the US where I grew up seized a Lamborghini from a drug dealer and turned it into a police vehicle. But not a stealth vehicle. Such cars aren't common in that part of the world and would always draw attention, so played up on that. It had very visible lights, police logo, and something along the lines of "seized from a drug dealer" emblazoned on either side. That was always the car they used when they did school visit to talk to kids about drugz.
