Just found out that these are Volvo " Orpheus " wheels, apparently quite rare.
There is a bit of info here:

One of the chaps states that "they will fit 850/V70/S70/C70 WITHOUT spacers or any changes needed. " Not sure if thats true or not but I can't see why not! I haven't used them myself as they are not my wheels, selling them for a friend. To be honest i'm half tempted to tell him to keep them and buy them from him later when i've got some spare cash!
Anyway good luck if you decide to bid
Still open to offers by the way.
