Wheel trims on a '98 V40

Hi

Does anybody know where I (or more specifically my father) can get a hold of a wheel trim for a 1998 V40 in the uk reasonably cheaply? Have tried both Volvo and an Independent volvo specialist in our area (Ayrshire, Scotland) but both are wanting £40+ for what is essentially a bit of plastic. Have also phoned round a few breakers yards - no luck so far. If I recall correctly, there were two types of wheel cover for the V40 at that time - although I can't remember what they were called so unfortunately I am unable to be more specific, it is the one with a black 'volvo' logo between the four holes for the wheel nuts and it has round holes around the outside of the trim. I did find the following on the back of one of the other trims if it helps:

Volvo

any help much appreciated

cheers
