David your assumption that Ford needs to be "saved" is wrong in the face of what we've been seeing lately and their "Way Forward" plan that's been working to evolve the Blue Oval.
It's going to be several models that set Ford apart. It's going to be the work that Alan Mulally has been doing with the "One Ford" and the fact that Ford has recently updated several solid models like Mustang, Taurus,Fusion and F-Series trucks while bringing new product like Flex and Edge to market.
Ford will survive because they're going to have the products and technologies to compete in a truly global market. Because of the Fiesta, Fusion, Upcoming Focus redesign and EcoBoost & Hybrid technology.
I'm sure Ford appreciates the praise of the Fiesta, it's a praise worthy car, but let's not peg our hopes on just one model or understate all the hard work that's been done.
