Example: Full size truck with the most US parts and manufacturing - the Tundra.
And then this from the Detroit News.
Toyota Motor Corp. also is the most American car company, according to the rankings of the index in terms of U.S. content in its cars and trucks.The methodology might be a bit skewed since it only counts total parts and doesn't have a scale for labor intensive parts like engines.
Still, Toyota has maintained it's workforce in the US while the US based makers have downsized dramatically.
Will Toyota keep making cars and trucks here when cap and trade is enacted?
