Condensation in car

[126 carat]

Hello all, I have w126 and she is suffering with very bad condensation inside I was wondering if there was some common course for this problem on the w126 please help as it's driving me round the bed

Leaky sunroof, front ventilation scuttle or rear window to parcel shelf metal would be my first guesses.

I do have a hole in the rear parcel shelf panel , something I haven't got around to getting done yet

Unfortunately it does mean it's leaking somewhere. They tend not to mist up at all normally.
