Locally where I'm from I inquired about the same thing... I was going to buy an ex-cop car, make it look exactly like a real cop car, minus the real phone numbers and Calghary POlice, it would just say Police, real working lights and everything. The officers I've talked to about it said it would be just fine, as long as I never pretended to be an officer, used the lights for anything other then offroad (show use), or make people think in any other way I have authority.
