If youre trying to please a "buy american" acquaintance, that won't matter even if they were assembled in the USA... since the "profits go back to Japan/china/etc".
I go through that every time I buy vehicles with a "friend". Of course, when I bought my wife a new Chevy, I didn't hear anything positive like "finally.. good for you!"
But, I don't pay much mind since he told me that I'm adding to the trade deficit (which I agree with) and then stated that we need to pay back that money (ie, the trade deficit) and that's why we as a country are in such debt. I think my head spun around a few times and thought "self... it's just not worth it after hearing that".
If that's not the root of the question, I apologize. I just love sharing this story.
