Boxster got caught in a "flooded road"

So if the water didn't pass the sill where did t come from? The main cause for water behind the seat is the rear drains or holed foam tray. The fact you said it was raining heavily also lends weight to this being the cause. If you can feel the water atop the carpet then the foam insulation underneath will be much wetter.

Well the water didn't come in from the side (doors) but it did come from the bottom of the car, since I guess the bottom of the car is notsupposed to be 100% sealed and waterproof ?
Plus the rear bottom carpet ( closest to the firewall ) got wet on both drivers and passengers side. I have already checked the only drain hole I know ( which is under the roof plastic on the drivers rear side) and it was Clean

How and what else shall I check ?

There are several drain holes to check. Front and back. A quick search will provide a lot of info, Youtube, etc. I suggest that you test them to verify they are flowing correctly. They are small diameter lines that could be clogged in the middle? Here is a couple with diagrams.

Thanks for the links. The second one seems to be for 987. I checked this https://sites.google.com/site/mikefocke2/_/rsrc/1259691725220/986drains-full.jpg
And I can't see any drain hole that is on the passenger side. If there was one there, it would explain the leak on the rear bottom carpet.
