I don't understand how these cars can be compared?
£16,377 Focus ST170: Not fast, ugly, crap interior and a Ford
£13,200 Clio 172: Significantly cheaper than all of them, nice car but very small.
£15,202 206 GTI(180bhp): Powerful but small, £15k is a lot
£14,691 Mini Cooper S: Very nice but not my scene and will be £17k with options, easy.
£16,100 Seat Cupra PD: Nice car, probably the one Id go for on this list
£17,440 Honda Civic Type R: Amazing engine but nah
Assuming your budget is £16k, I don't think Id look at new - as it looks like you want a Hatchback I would be looking at 2 year old Audi A3 1.8Ts
