I also read some very interesting comment claiming that the price increase is to help GM and Ford sell it's cars in the fear of anti-import sentiment and possible new laws from our Congress.

I'm guessing Toyota is not that generous. Beisdes a $300 advantage won't help Ford and GM. They already have to discount and rebate cars to 1000's less than Toyota to sell their cars. Most folks purchasing Toyota won't be interested in saving the $300 enough to sway them to Ford or GM
