How can you tell....

[Ace]

i am about to buy a set of rims off of someone but am trying to make sure that they are OEM rims and not replicas....does anyone know if there is a way to tell OEM rims from replicas? thanx in advance....

All the replicas I've seen either don't have all the various codes and stuff cast into them (BMW logos, PNs, sizing, etc.) or the text is all 'fuzzy' and barely legible.
