Did the roof this morning. Fairly easy as everyone has said, some clips came away when removing the old one but easily remedied. I think you have to be reasonably courageous in tackling this and pull fairly hard to get the clips out, but they do come out ok. Spent another half an hour checking that I had done it correctly! Can’t believe how good the result is with very little outlay.
Happy Christmas everyone.
MB dealer contacted me 2 days after I ordered to say it was in, removed the full headliner at home and fitted the new pano headliner in the dealers car park in about 5 minutes, but at £211 its an expensive piece of plastic but hey ho the wifes happy.
