I have a used slightly damaged wheel that fits a 2006 G55 (I think). Part # A463 401 1302. Measures 9.5 x 18. Slightly damaged at the rim edge on the outside. Can be easily repaired by Wheels America for $129.00 at several locations.

I don't want to just scrap it out so let me know what it is worth to you. I can send it to Wheels America for you and they can send it on to you.
