You're oversimplifying this situation, George. Those Ford Fiestas you're talking about are diesels. Diesel cars don't sell in the numbers required to build a plant in the US. If the price of diesel comes down, there may be a market. But only a fool would roll the dice on diesel cars right now, if their entire future depended on the outcome.
There are many problems involved, not the least of which is unstable credit markets that are keeping Ford out of the market for funds to build new plants, as well as to do enough research. What they're asking for is loans.
The US car manufacturers are facing a heap of troubles. But the new CEO, Alan Mulally, probably is the best thing to happen to the company in 50 years. It's too early to tell whether they'll make it but I doubt if you or anyone else could come up with better management right now.
