Still leaking

[Jinx]

I have a 2003 Boxster. I have owned it for 2 1/2 months now.
When I first cleaned out the interior the carpet was very very wet
Soaked in fact. Drivers side only. Got it dryed out and had the local dealer blow
Out all the drains. In past rain showers carpet was moist. Heavy rain
Today and carpet is again wet but not nearly as bad as before, but still
Wet. sitting in drivers seat wet from middle of back engine cover to
Left edge. carpet is wetter the closer you get to the left edge. Any
Ideas on where to check now. Any pictures and advice would of great
Help to me. Thank you, jinx
