like a wind deflector

I think that might actually be a sunroof deflector that they've attached to the tailgate..

It definitely looks like a part that's been re-assigned from it's original purpose. I can't find another for sale or pictured at the very least. It looks better than most spoilers you get though.

Nah its an official part, I imported one then sold it one here a long time ago (not sure if original buyer still has it though). I think it's meant to be a sun visor for the rear passengers. I just bought it though cos i thought looked cool and hadnt seen one before. haha.
