You just made my day! My window sticker clearly says "final assembly point: Los Angeles." I've been labouring under the delusion my car was domestic. I just Wikipeda'ed Nissan's assembly plant and LA isn't mentioned
I've owned many Japanese made cars and Japanese American made cars and have always felt the Japanese made cars are better.
Maybe the car is made in japan and then shipped to LA where they make any final tweaks for the US market maybe?
Uk zeds have the nismo kit fitted in sunderland and not japan IIRC
