Price for OZ F1 Racing Cup wheels?

[GTU89]

Okay, they are 17x7.5, 5x100 and another bolt pattern. Previous owner caused a little curb damage and one center cap is lost.

Anyone have an idea of what a good price baseline would be? it would be with matching sized half tread tires.

I can't find any recently for sale, and the prices have been all over the place from what I've found. (mostly subaru forums and vw forums)
