Umm... If it has any electronics on board, chances are they will be foreignly sourced, right? That goes for battery cells too, i'd imagine.
Also, doesn't the auto industry have to say how much of each vehicle comes from different countries? IE X% is usa sourced, X is asia, etc? I thought i heard a few years ago that many of the Japanese makers actually had more parts/assembly in the USA than many of the big 3.
My point is that finding anything electronic that is 100% USA will be tough anymore.
Thats kinda my whole point about most everything! Like Dennis said electronics have basically been like that since I was still in school. NAFTA, CASTA and all the other STAs has spread that to basically everything. Even a lot of foods.
