If the base price of the ST is over $25k I don't think many people will buy it, I've been eagerly awaiting the release of this car but if it's over $25k I'll just get a base model GTI, even if I am afraid of VW reliability I can't justify spending money that starts to approach the Mustang GT, BMW 1 series, Challenger R/T, or the Acura ILX (if it lands up being more powerful than the Civic SI).
I want a car that's quick AND comfortable. If I need to spec out the ST past $30,000 to make it comfortable it's not worth the money to me. The GTI is pretty comfortable stock, the Challenger R/T and Mustang GT aren't as comfortable but offer a whole lot more power.
I'm ranting. Ford, give the Focus ST a base price a hair under $25,000 and keep it under $30,000 with good seats, xenon lights and whatever other options you'll require to get those two options.
