I have a 2011 750Li and want to add a roof rack...base support and box, like the 460 Roof Box. When checking out accessories on the BMW site, it doesn't show any of these being available for the Li model, just the standard wheelbase model. The BMW base support should work as the car has the built in channel anchors, but can anyone confirm whether the roof box (460 or 350) will work? I believe they require a specific support dimension front to back. Can't imagine why BMW would change the distance between the anchor points on the long wheelbase model knowing it would prevent using all of these accessories...especially with the postage stamp trunk space. Otherwise, if someone could provide the on-centers measurement between the roof anchors, front to back, on a standard 2011 7-series, that would be great. Thanks. Cheers, Brian
