I was referring to the fact that most sunroofs are not designed to
form a watertight seal with the roof. They just fit tightly enough
to shed most water, and whatever leaks in at the edges is drained
by a gutter and drain lines that run down to the bottom of the car.
Maybe your sunroof has too much play (looseness) somewhere,
allowing it to lift a bit at higher speeds and then drop back when
you slow down. I have an 850, and it doesn't do anything like
what you describe. I doubt that your S60 should, either.
