Not sure about that! If £550's the ball park then I'll just pick up the 7.5" fronts and 9" rears on E38 for £300 unfurbed...
Steve - If you do pick them up and want standard Cupra wheels give us a shout
Im saying £550ono is fair,they have brand new yokos and adaptors and just been refurbed.
If you got that set of off E38,you'd have to get them refurbed get adaptors,tyres and it cost you between £650-800
Its up to steve gti if he wants to swap for a standard set of cupra alloys worth about £150-200max
