Mine had/has (still working on changing it)
Big boost gauge on the steering column, couldn't see the speedo - Took it off, currently deciding where to relocate it (Need some hints, NOT A PILLAR)
 
An unwired Turbo Timer (It was unplugged, and the body half of the wiring wasn't on it at all.. don't know why they bothered - took it off, not relocating it)
 
Blitz Atmo BOV, currently looking for stock replacement, or a nice aftermarket one (Kinda looking for suggestions for a plumb back BoV)
 
It had a damn big (3inch wide, 4.5inch long), metal Transformers badge on the front, of which the sticky glue took over an hour to carefully remove.
 
Apart from that, nothing too ridiculous. Needs a lot of work still though.
