up! as a 5-door

Dear community, especially interesting at the studies that VW has shown to the IAA presentation of up!, I find the seinenahen versions. Above all the cross-up!, which should probably be a pretty good harbinger of the 5 door up!. On the pictures I noticed, however, that the Sparzwang could probably also mean that, as with the Toyota Aygo and the sister models, the window will probably not be retractable at the rear doors. But only possible … at least probably I do, if I look more closely with the rear disc on the pictures 🙂 I once attached two photos … I hope you can see the small anchor point in the disc. Was anyone on the IAA and has seen this more closely?
