You guys have to read down a bit:
TOO PRICEY TO IMPORT
First of all, the engines are built in Britain, so labor costs are high. Plus the pound remains stronger than the greenback. At prevailing exchange rates, the Fiesta ECOnetic would sell for about $25,700 in the U.S. By contrast, the Prius typically goes for about $24,000. A $1,300 tax deduction available to buyers of new diesel cars could bring the price of the Fiesta to around $24,400. But Ford doesn't believe it could charge enough to make money on an imported ECOnetic.
It is the Brits fault with their free healthcare and the like.
