Eventually, I replace roof cables and gear on my own, and now the roof works perfectly, and I can use also the boot. Then, I replaced all the interslides of the roof because two of them were broken. And now the roof close perfectly, too. I spent 260 Euros. If can understand italian language, here the complete instructions that I wrote. http://www.citroen-club.it/forum/viewtopic.php?f=48&t=20272 http://www.citroen-club.it/forum/viewtopic.php?f=48&t=20586 Good luck!!
