Hi
I've seen a couple of vans advertised for sale (reputable garages/agents) recently with what seem to be dark streak marks running vertically downwards underneath window frames.
Is this anything to be concerned about or is it just where the rain channel directs excess water to drip from the frame and run down the bodywork?
On one van it was prominent on one side below all the windows but non existent on the other side.

Just where the rain runs off the dirty roof then over the window but should be easily cleaned off

Not always just "dirt from roof" .. on older vans it can also be a sign of the rubber window seals perishing.. the 'black' is coming from the rubber.

Carefully inspect and look for signs of cracking around the seal.. especially at the corners.. if bad they will need replacing ..

as above its the rubber degrading basically the rubber dries out losing all its oils one of the tricks is to use stuff called "grip" its a tyre softener helps to preserve the rubbers or another old school trick is to wipe the rubbers with a silicon grease yet again help to preserve the window rubbers
