BMW Response Vehicle Owner's Manual

I can't imagine many people have this in their book-pack. BMW supply cars directly to UK Police constabularies, so this is their in-house user manual for controlling the lights and sirens no less. It shows even the switch-gear being factory fitted with buttons to match the BMW fascia, though I am not sure what level of spec mine had. I guess this is another easter-egg gift that comes with owning an ex-Police car, along with tons of extra wiring and air-con that stinks of sweat...
