In the UK, the highest trim new-gen Ford Focus is 18,825.00pounds = $33,000USD (out the door price, not MSRP). And this is not fully loaded, just the highest trim with no options.
This is for a regular Focus, the high performance Focus ST in your link is going to cost far more. Let's say the premium for the Focus ST is another $5,000USD (actual pricing not released yet, and it's going to be more than this), so you willing to pay around $40,000USD for a Ford Focus?
Even $33,000USD for a 'regular' Euro Focus is not reasonable for Ford USA. N. American and Europe markets are completely different.
