[quote=Ddey65,19021] Sadly, I read a recent copy of Consumer Reports magazine, indicating that there are no American plants that build American cars anymore. [quote]

That's not true. There are tons of American cars built in American plants. There's even two American plants in my hometown (Lansing, Michigan) that make the Cadillac CTS, STS, and SRX. Plus a plant that makes GM's new crossover SUVs (Saturn Outlook, Buick Enclave, etc...).
Along with those plants and the ones BeanBandit listed, there is also:

Dearborn, Michigan: Ford F-Series
Wayne, Michigan: Ford Focus
Flint, Michigan: Chevy Silverado
Detroit, Michigan: Jeep Grand Cherokee
Toledo, Ohio: Jeep Liberty
