Thought I'd offer these pictures as a cautionary tale for any of you that are considering permenant decals for your vehicle. This is my new car for this year. It is a 2001 Ford Crown Victoria Police Interceptor. It comes from the Michigan State Police and had less than 85,000 when I got it.
Because of the aftermarket equipment (spotlights, pushbumper, radios, lights, etc.) I almost had to place decals to avoid law enforcement thinking I was trying to impersonate. I really wanted magnetic signs, but they were WAY expensive and would have looked like . . . well, magnetic signs. So I went with permenant decals.
It has been a nightmare. This is my daily driver, and everywhere I go I get questions or comments. Stuff ranging from "What are we getting" to "I don't see no turnaders 'round here" to "What do you do with the storms when you catch them?" I highly recommend that if you're considering permenant decals to NOT do it, at least not unless you plan on driving the car only for chasing.
On the plus side, LE seems to like the car and I have had no problems with them. You don't get pulled over in this car unless you're being really stupid. Also, it has speed and can take abuse from the highway. I've spent 25+ hours this week chasing in it and have been really happy with it. It looks pretty sharp when it's washed. I'd recommend a used cop car to anyone because of the durability, but learn from my mistake and steer clear of the permenant decals.
Edit: Don't want to get into the light debate, but there are lights on the car. Most of them are unseen (strobes), but there are two mini amber LED lightbars on the rear deck. They don't stick out too much. I put lights on it because with my EOC I have had to work traffic control and needed the lights. When chasing, I almost always will just use my hazards on the side of the road. Also wanted to mention the camera mount: I got one of the suction cup mounts and used four screws to mount it on my dash. It is very sturdy and looks professionally mounted.
