I had a popup sunroof fitted in my brand new (at the time) 1986 Astramax van

It was brilliant, loved it to bits. However I always knew that would be a leak problem for someone one day

Mind you, the doors leaked from day one and used to fill the footwell from new; I expect the floor rotted out before the roof failed on that one
C696GRO where are you now?
Tigger.
