i bought my car under the impression it was completly standard, when it arrived i found a few extras on it;
HKS Adjustable actuator
HKS Mushroom Filter
Apexi Cat-back exhaust
HKS FCD
Blitz dump valve
TRD Plugs and leads
uprated clutch
xenon lights,
also found snow wiper blades, their weird lookin things! a letter from someone with hearts and x's all over it, tried to get it translated but my local take-away got offended when i asked them! also found two tickets to an opera in tokyo from '07.
i found far worse in my 205 tho, a few (empty) packs of liquid viagra shoved down the back of the seat, few jonnie wrappers down there too!
