I have an OEM Mtech Rear Bumper that I just bought a few weeks ago from BMW dealership. It is brand new, never installed. It is primed and needs to be painted. The bumper is non-PDC and doesn't come with diffuser. Pictures will be up tomorrow. I'm asking for $400 PICKED UP NOW!! *price lowered. $600-650 shipped.
Currently looking for only local pick ups unless you want to be pay for shipping(shipping is $150-200). Located in Rowland Heights, CA.
* UPDATE Pictures - (sorry they are from my iPhone but I've included a picture that shows its authentic oem)
