sabbath

Hi guys just bought a protege5.,,, okay when i bought it of this fellow I noticed the floors in the front were soaked.,, he said his parents left the windows open and i believed him, as soon as i got home with the car i went to town and took out all the seats and removed the carpet I immediately shop vac an inch of water of the floor! when i went to bed last night the floor was bone dry but then it started raining. I noticed little streams of water coming in both sides of the car where the floor pans meet the firewall (right under the pedals on the driver side) and in the same spot on the passenger side. I don't see any cracks or abnormal rusty spots around the windshield....any ideas on where this is coming from? thx in advance.
