The headlights are truly ridiculous and clearly designed by the same genius who believed hiding the fuses behind the glove box was a master stroke along with placing the roof motor in such a silly place.
I can do ANYTHING on my Z3 but when it comes to the Z4M I don't even bother. I pay the maintainer to do it. I have photos of his back covered in bruses after replacing the roof motor on the E85 through the boot. On the Z3 open the boot and there it is. And then the emergency release cable unhooked itself so if this roof motor fails I am done for.
