I did some searching (can't sleep) & I think these are the AVUS 3 piece af-m02 18/19. Does that seem about right to those of you in the know. It also sounds like I could get them painted a different color by AVUS ($$) though I'm not sure I want to go back to 18/19 - I like my 17/18 OZ Racing rims. As for cost, it appears the previous owner spent >$4k for this setup (eek). So I wouldn't even venture a guess as to what they are worth now.
If anyone has any ideas on a reasonable price I'll go ahead & post these in the for-sale forum.
