Obviously you are clueless. Last I heard, Hyundai's headquarters are in South Korea and many of their parts are manufactured in China.
South Korea and China appreciate your patronage.
Name me a car that doesn't have any Chinese parts, it certainly won't be a GM product.
Officially, Sonatas, at least in 2011 were manufactured using 41% U.S. made parts and 58% South Korean made parts.
GM is the one investing in China, it's on the 'net look it up.
If there was a non-union 100% American car company I'd support them, but there's not one.
