I'll join in with --the bar as part of the roof mechanism is in mine as well.
Also, through direct experience in the rain forest--the Giulietta tops are better than the Giulias.
On mine--at 80 mph only a few beads of water will come through above the wind screen--but only on the passenger's side.

The Giulia tops seem to allow water in from the sides as well.
Also, from direct experience in the rain forest. When parked overnight, make sure it is parked facing up-slope. When parked facing downhill, water rolls in from the rear deck and gathers in the floor wells.
Don't take the drain plugs out as they are too difficult to force back in. The new absorbant "chamois-type" cloths are very good at soaking up water.
