After a 250 mile cruise up the Blue Ridge Parkway in pouring rain in our ERA289, I am here to tell you that the soft top helps, but does not significantly abate the inflow of water into the car. Major sources of infow are at the center of the top where it conects with two little buttons to the windshield frame. Another major area is down the two windshield posts into the footwells.
Assuming that you can seal, caulk, etc. these two areas, the top is not too bad and for all of it keeps the rain off your head. It still is a good idea to pack everything securly in garbage bags...
