Even when everyone that wants one gets theirs it's still going to be fairly exclusive. TBH, I really don't see that many Fiestas driving around town, so the likelihood of spotting a Fiesta ST in the wild goes down even more. Only ones I've seen is the one at the dealership and the Ecoboost Challenge ones. Fiestas just aren't as popular in America because of their small size, which is really odd because something like the FR-S and Mini seem to be widely more popular for the most part and they are at least as small if not smaller... Focus STs will always be more popular as regular Focus' are selling pretty well and I see almost too many of them. I've seen one Focus ST in the wild confirmed and I believe I've seen another, but I'm not positive on it. So even those really aren't that commonly seen.
