The KA ST does look fine, if it actually ends up looking like that. Ford will do one, as the sport KA is popular and they'd definitely want a replacement.

The new Fiesta I'm still undecided on. It certainly looks newer and fits in with the kinetic designs of the newer Ford's, but I just think that maybe they have lost some of the sharp lines of the current one, making it all mk4 and wobbly again. Maybe it will grow on me. I should have taken the chance to see it at the motorshow, but I didn't get to as I spent over an hour on the Ford stand and all of that time was looking at the Focus RS.

Regarding a Z-S TDi I'd be surprised if Ford don't make one, as I'm sure the current one must sell loads.
