My sunroof is the panoramic one. I debated about getting it because of its size and the structural issues that might result from having a gaping hole in the roof, but resolved the issue in favor or the engineers at BMW having the design ability to fortify what remains of the roof to give the car the rigidity and structural stability that it needs. I hope that this leak (and the other fellow in another thread with his creaky sunroof) are not symptoms of a poorly engineered roof.
