18" BMW MV1 Alloys & Tyres Refurbed in Anthracite...Swap for other BMW Alloys !

I have a set of recently refurbished 18" MV1 Alloys from my E46 done in Anthracite with all tyres replaced 6 weeks ago...Goodrich 225/40/18 on the front & 225/35/18 Michelin Pilot Sports on the rear. Looking to swap for another set of BMW alloys in silver 18" or above....Must be in good condition with good tyres also. WHY??
