I have a set of Thule roof bars and feet that came off my BMW 3 series tourer with solid rails (fits MY 2012+). The bars are aluminium aero type 120cm long and the feet are Thule 753 specifically for the integrated rails, there is a fitting kit (4043?) in there somewhere as well.
If anyone wants them before i stick them on eBay let me know, i will clean them up a bit but they are fully functional, a few scratches as you would expect, with full set of keys to lock them in place, they have the T bar system as well which means you can use T bar accessories like bike carriers etc easily as well as grab type fixings such as on roof boxes etc. I used them once a year when taking my roof box on holiday and for the odd bike escapade.
They are about 6 years old but that's irrelevant really, as they don't rust or anything. Paid about £190 at the time, looking for about £60 for the lot collected from Ringwood, Hants would be easiest or can post at cost on top.
