Wet patch.......

[RUSSELLM]

With this recent rain, I've noticed the roof lining is getting wet, down the side of the rear window.

It starts from the top of the window, I'm guessing that the rear window seal is knackered. Has anyone else had this.

Also, on this car, the top of the front windscreen has a rubber seal, which you can lift up. Is that supposed to happen ?

Your water leak does look as though its through the rear window, maybe some silicone under the rubber would seal it or get a windscreen company out to reseal it with thier "special" sealant.
For the second part, I haven't looked, but the windscreen seal isn't there to seal, just to cover up the joint, so you can lift the edge up, the sealant is down in the bottom of the gap.
