it's a sun shade that resides in the back window. A luxo option standard on most 7 series e38s (and maybe later year e32's? I don't know, shogun would) in the US. I guess it'd be good if you've got occasion to cart around heads of state and what not, or if you just want to protect the leather seatbacks a bit more from the angry sun....but, from my perspective, I'm always in the driver's seat, so it doesn't affect me, and I rarely have passengers.

yes i think you are right shogun,my 1990 car is a euro spec car,although as a sport it has its own option list....but with pundit i have rear headrests,and dual zone auto a/c and m tech wheel with electirc leather recaros.I have headlight washers and intensive clean,and i have never seen a e 34 witout a sunroof.I would like a rear sunshade to protect the rear seats and head rests too.I dont think we had SE spec cars here...
