I think a Mk5 Z-S with a 1.7 vct is regarded across the nation as the car Ford should have made seeing as it has the same chassis and suspension etc as a puma anyway. Plenty of Fiesta Afficionados will testify to this and I know at leat three companies have started business and continue to trade based on the fact. You could check out UKFN or ZSOC.com or any other fiesta club to check this out.
