Detroit Wheel & Tire says on that eBay listing that they are:

20" FACTORY ORIGINAL BMW X5 WHEEL
Wheels came off a 2009 BMW X5.

So is that just completely bogus? The $1399 price would make me think they were replicas, right?

EDIT: After looking more closely, it says they are reconditioned. But I'm still not sure what they are. They don't look the same as those X6 wheels to me.
