Volvo C 70 Convertible Water Diversion Needed

After years of longing, I have finally purchased a convertible, woot. It’s a 2002 Volvo C70 and this will be my primary vehicle, double woot.

Here’s my problem: When the top is up, and it is raining, and I open the door - a steady stream of water from the roof pours into the car. Nothing appears to be missing so this strikes me as a weirdo design flaw?

Anyone out there have a solution?
