JDM can be nice in moderation, but many use it as an excuse to show off their money... For example, when I finally get some Recaros, I think I might go a little JDM and pick up one of those no-arm-rest ebrake covers off the JDM Type-R, and I wouldn't mind some of the JDM yellow foglights either (But those are insanely expensive for what they are...). But people go overboard and buy shit like the coin holders, heater control console, and my personal favorite, the JDM ITR taillights (Which basically look exactly the same as the 94-97 lights, but they're JDM and off the ITR y0!) and it's mostly a waste of money...

So while going JDM nutty is better than rice in my book, taking it beyond general aesthetics and using it as bling status ruins the feel of what would be an otherwise clean car...
