I got them new from dealer but at a reidiculously cheap price, they had to be machined to clear centre bore as this is the only XJ with them fitted in UK they told me.
Also there staggered and I had 4 new tyres with them so wouldn't want to say how cheap I got them but go to Wheel Mania Birmingham or you can buy them online.
TBH I made money as I flogged a set of wheels and had some money left so was a bonus for me lol
