The following links are to YouTube videos showing crash tests performed on Chinese-made vehicles.
The reason this is relevant to Americans is that Chinese manufacturers are being courted by Chrysler and General-Motors (specifically Chevrolet) to sell them vehicles to be re-branded for the US market.
Chrysler is in talks with Chery (get it? Chery as in Chevy) for this purpose. I believe they are considering 2009 or 2010 to begin importation. Here is a video of a Chery Amulet being subjected to an approximately 35-mph frontal impact. My advice? Any sane person's advice? Avoid.

Here's a Korean-made Hyundai that also does exceptionally well, at a mere fraction of the cost of the Infiniti. It's not a conspiracy by the automakers to only protect those who can afford to be protected.
http://www.youtube.com/watch?v=NwtvhkRBxQMCurrent Mexican- and Canadian-made American cars fare just "okay", with a few extremely poor exceptions (such as the GM Daewoo products). Some of the videos you'll find of Pontiacs and Lincolns and Dodges are startling and embarrassing. However, American-made Toyotas generally have done very well. That being said, it doesn't seem to have much to do with price, but rather engineering prowess or, and more probable, sheer lack of motivating factors.
I stand by my assessment that the modus operandi for modern capitalism is to produce the lowest quality product with the highest profit margin that the market will possibly tolerate.
