Dont know if its a sticker (transfer) accross top of nose - could be just painted a different colour to highlight the nose cone. I wouldnt have thought the rear spoiler was available but i think with a bit of effort one could be made up out of fibreglass.
It would take much to make a "replica" - some wolfrace alloys - grey tint on nose- nifty rear spoiler- front quarter bumpers and hey presto - a Black Knight lookalike . The interior may be more difficult though , I heard it had carbon fibre seat frames and a drinks cabinet and sauna built into the back - only kidding !!! But a drinks cabinet - now theres an idea.
Mines a double JD - Cheers Jon
