Hi there buddy, i went from a saph to a st24 and must admit i was blown away with the beautiful power outlay of the 24 and i'm told it's better on the 200, but if your looking for the raw speed and accelaration of a saph then there is no way, but as for the drive, i have driven new alfa gt 3.2 v6 and must admit the mondeo feels smoother. plus is much better on fuel than the cossie, although try and get 1 with ffsh or at least done at a reputable garage, can go quite bad if not looked after. good luck
ps. you can pick a good 1 up for about £2500 30+mpg if your not driving like a loony
