I'm a bit confused on this Murano question. If Origin becomes US - as argued, and I don't particularly disagree with - build according to wiki was only in Japan (Z50) and then for Z51 J and Russia. US builds only started with 3rd gen Z52, along with continuing Russia and new addition China (but not apparently Japan).

So for Z50 and Z51 if we make origin US, we need built in J, and we should have each made for filled in, not deleted?? Even if this means for 2003-05 when it was only sold in US, where they should all be Origin US, built in J, made for US.

Or am I missing a trick here?
