After parting with my Clio 172 which was going to be my track car project, my heart still lays with the fords having had them all my life !!

My question is what to buy ??

Mk6 Fiesta ST

Mk6 Fiesta Zetec S

or a Focus st 170

Any sugestions of whats best would be appreciated

I get told Zetec S as more punchy being a 1.6 but feel is it too under powered
