[quote=""Woofer""]Hi k2
I have had 3 E61's with pan roof with no issues , keeping the mechanism properly clean & greased is part of the service schedule now , likewise I have had 2 e70's with the same trouble free pan roofs, one sold at 4 years 60k , the other at 2 yrs old , all were bought new or with BMW warranty which I'd recommend given the costs. Dirt in the mechanism is the killer especially grit from bird droppings, also flexing can occurr with off road use that might present the potential for a crack!
I' ve now got an e53 as a runaround with the normal roof and it is nowhere near as nice to live with .
Good luck!
