Wheel fitment - What fits!!

[cjp2k]

Hi guys, parents are getting a new polo, and have been using winter tyres for the last couple of years, we already have a set of tyres which are the correct size (185/60/15), same as the summers as standard as far as I am aware, but need a set of wheels to put them on, any idea what wheels fit

Cheers
