Friend of my brother's bought a Crown Vic at a police auction. An unmarked policecar that still had the "I support the Police Department" bumper sticker and the Brotherhood of Police Officers window sticker on it.
Awesome ride and it was absolute badass on the open road!
I gotta say, the kid in me is very jealous of that!
I gutted previous Vic (pbui) and rebuilt it with cop and sport parts. On the outside it was a grannymobile, on the inside it was at least Interceptor spec (in places even better).
I had a lot of fun in with that car.
Back in the day, I had a girlfriend who bought a used police car... That thing flew, and when it wasn't flying, a tap of the brake pedal, and those big lights would come on in the back window, and any officers investigating the parked car would back off... ;-)
