I'm not a fan of the style of the 16" wheel on the ZS but I agree that the ST would look far more purposeful on a smaller wheel, and I reckon the handling would be all the better for it too (see Clio 182...).

Its a shame that Ford felt the need to go with a 17" wheel just to satisfy a certain proportion of buyers, they could've at least given us the choice of wheel like you get on the continent.
