CarDomain seems pretty sure the Fiesta is going to start at $12k. I don't really see that happening - all indications are that they're going to peg pricing to the Fit. In any case, they're 2 very different subcompacts. The Fiesta just isn't going to be able to compete with the Fit for interior space/versaitility. You could load a barbeque grill in the Fit with very little problem, but I think the Fiesta is going to be a little more cramped.
Either way, nobody's going to be able to rightly compare them for a good many months. Dang, when's the US-spec coming out?
