He's cool like that (lol). I've seen a USDM-spec trend in Japan.
Toyota, Honda and Mazda guys seem to do the same thing.
A whole scene 'loves' USDM bumpers, orange reflectors, US license plates.
The closer to USDM spec or 'ghetto-fabulous', the better.
Reminds me of how chrome tailights for many cars are advertized as 'Euro-look' (no clue how?) in the US and 'Lexus/Altezza-look' in Europe. With Lexus traditionally recognized as an exotic US brand (*cough* rebaged needless mark-up Toyota *cough*) hence the Altezza reference (Toyota Altezza was the JDM name for the 1st-gen Lexus IS as sold in Japan). I guess they sell better this way, sounding exotic on both sides of the pond for vastly different reasons.
