I can get the BMW roof rails for $213.00 but not sure if I want it now that I have seen the whispbar option and even the rola RBXL option too. I have the race bike racks for the BMW bars on my M5 so I assume they would fit on the t-shape fittings on either rack.

I like the flush look of of the rola and the whispbar. On the whispbar it says that the s46 bar or the rail bar is not suitable with sunroofs. Anyone have this and had no problems? Otherwise I can go with the rola RBXL which seems to be better priced and sold sits pretty flush.
