This thread has the potential to get out of hand but for now I'll keep it open.

JDM is yet another style that people have turned into a huge bandwagon and blown up because that is the nature of people who modify cars for a hobby and/or living. It always happens.

If something is only available in Japan and is a noticeably better part than the US-spec version then I can sort of see the point, same deal if a particular aftermarket item is only sold in Japan. But stuff like swapping to a gauge cluster that has the wrong odometer reading and a speedometer that reads in km/h (just as an example) strikes me as monumentally stupid.
