First Custom show cop car

I just started working on my first custom cop car. It is a 95 caprice ex-squad. It has the LT1 350 5.7l small block. I will be putting tons of horsepower and torque into the car I want to put around 800 horsepower in the car when it is finally done. I haven't decided if I want the traditional black and white color, but I am thinking of doing a custom paint job but not sure what will be on it or what colors haven't gotten to that yet. I just started fixing the small rust holes in the rear fenders, and the small rust patchs on the roof which wasn't very hard to fix it only took about two hours. The reason it has a few rust patchs on the roof is because the officers park there cars in the parking lot and it must have been parked in the exact same spot everytime because they got there by water continously dripping on the same spot. So besides that it is in really good condition. It will have the original police lights on top the diamond shape ones that were originally on there. It will have light bars on the side windowsand in the front and rear windows. There will also have the taillights, and headlights will be able to flash those are actually already hooked up, I will be putting the police lights in the grill. The interior will get a total makeover. Depending on the paint job will make a difference on the colors for the interior. But I am putting in two six belt racing seats in the front and the rear bench seat will be taken out and replaced with two bucket racing seats probably also ending up being six belt racing seats. It will eventually have six 12 inch JLAudio subwoofers in the trunk with three amps. It will still have speakers in the front doors. There will be four speakers instead of two speakers in the back window. The windows will be tinted to about only 5-10% visibility from outside. The dash will all be taken out and replaced with painted fiberglass. The door trim will be also replaced with leather and painted fiberglass. I want to put 22" Diablo Transformer rims with custom paint also. It will have Edelbrock 3" true dual exhaust. that is pretty much the only ideas I have right now.
