Involuntary soft-top tightness test

On our recent trip to Vienna we encountered on a strongest storm ever I've driven in with my Saab 9-3 convertible. The rain was so strong as if someone would take a monumental water tower and throw its content multiple times on the road. Visibility maybe 20 meters, some cars were standing, for these conditions the back fogligths were o.k. (which is not in weaker rains).

Concerns about my soft-top tightness came and I remembered myself about the "1,500 liters of water is sprayed over the Convertible’s soft-top in a special chamber at the Magna Steyr production plant to check weatherproofing." mentioned in the well known text about Saab convertible testing.

Result of the tightness test : not a single drop got inside. Fantastic and my confidence of the roof in the rain is now 100%.

Here are two pictures taken by my girlfriend from that storm. The first shows the mass of water with fastest wiper speed and on the second she even catched a flash.
