I sold my car a few years ago and still have my rear bumper sitting in storage waiting for a new home.
It's a Rieger rear valance molded to a OEM German rear bumper. The rub strips have been shaved. It may have light scratches from storage, but otherwise it's very clean.
I'm asking $500 for it.
I'm located in the bay area (San Jose).
If you decide to buy the rear, you can take the front too as I have no need for it. It's been cut to fit a FMIC & has a small crack + needs new paint.
But the rear is super clean. I had it done and strictly left it in the garage for the remaining 3 years I had it. Literally took it out twice for a VW meet.
Let me know if you have any questions.
