Unstickered police cars, illegal?, Have you seen these? Options

Maybe I'm new to this or my town has a unique police force-but here is the story. I get pulled over one day this week, and the police car that got me was a Dodge Charger, that had NO stickers designating it as a police car. But the people in the car were DEFINATELY police officers. In my area of the the U.S. (im not sure about other parts of USA), the cop cars we have are Ford Crown Victorias, Chevrolet Impalas, and a few Dodge Chargers. I'd told a friend and he asked me if that was illegal and I didn't know. At a glance you couldn't tell it was a police car, but the siren light were tucked up in the grill and headliner. So I'm asking if any of you have seen police cars like this, or had this experience?

I've seen a domestic cop car in aftermarket parts such as a spoiler, body kit and badass graphics. The windows were tainted Jet black and the body had some nice designs and curvy waves it even sported some rims that stick out but they were black rims that looked nice. The funny thing was, I was driving for my job and was doing 60 in a 40 zone in a small town and spotted this car. It caught my attention and I actually slowed down to take a better look at it since you don't see domestic cars that looked that great everyday. Turns out the Graphics said, POLICE and the tags, "goverment property Unit-***" Sure enough inside there was a fat cop waiting for his prey holding out his scanner. He was behind a building which made him looked like a parked car trying to show off. I was Shocked.
