I'm on ZSOC too, its a very knowledgeable place but its very very quiet. yeah the rust is what let's these down, mine has some surface rust on the rear arch that needs sorting.
mine is standard apart from the fiesta ST brake conversion on the front. That's worth doing for what it costs and how easy it is to do. there's other things i want to do to it but it's getting round to it, I'm hoping to do the puma conversion eventually,
