It's interesting, because the Fiesta ST is priced below or at least comparatively with its main competition: Fiat 500 Abarth, Mini Cooper S, and Veloster Turbo. However, it is simultaneously priced too close to the Focus ST in my opinion. Only about $2000 in difference between similarly optioned Fiesta and Focus, a bit more at higher trim levels. And the Fiesta is much more likely to be cross shopped with the Focus than the Focus is to a Mustang or even WRX.
