One of the things in love about the Caren's obviously is the amount of space. But I've got a roof box and no where to store it, so need to fit roof bars. My version has the little slots that take a foot pack and then fitting kit. I think it's a Thule 753 FootPack for this version. I'll be buying the cheaper Halfords fp3 alternative of course! Anybody done this and can confirm? I'll take pics of fitting slots later. Definitely not fitted rails.
