well...im not clear abt that my self.
but i think the carz in US are fully loaded with lots nd lots of thing regarding to everything.engine,comforts etc.i mean they hav(lets take civic) the biggest rimz,most bhps,max. body kits as stock etc.
JDM is japan domestic model.the carz(let it b civic) produced in japan its self.
euro is european manufactured...like accord cl7 or 9.
u see,the jdm accords' shape is that which honda atlas ppl give us,but euro is what is cl7 or 9...
:S am i right...?? i dnt know my self.but atleast that what i THINK.dnt know wats the purpose of giving different models.might b,ppl in US like to pay more if they get more,ppl in japan like pakistan,r not willing to pay more even if they get more.
