sflori,
I have a really old Yakima on a Toyota Corolla that was my daily driver. I think I'm going to transfer it over today to see if it fits and I like it. If this seems to work with the sunroof, I'm going to order another one (Thule probably or maybe Yakima Steelhead series).
My Yakima has locks for the towers and bike but the bike "channels" that hold the bike tire and front fork unbolts from the rails with thumbscrews--completely defeating the purpose of locking it. DOHHH
I've never had a bike stolen or messed with while on the rack, but I usually won't leave it on the rack if I go shopping or something.
Sure wished MB would bring a C class wagon with the 2.2L CDI engine in it too the US for approx $25K. Of course, I wished I was Steven Tyler married to Christina Aguillera also, so I'm a big dreamer.
(OK, so that's not a good example.)
