Bought a used 2007 pontiac g6 gt yesterday and that night i found that the floor board on the drivers side front and back were very wet. This morning i used a rug shampooer and sucked the water out and dried the floorboards. I rinsed the car off with the water hose and left the car for a few hours. Came back and the floors are soaked again same side front and back. I dont think it leaked when i rinsed it the seats doors and windows were dry after i rinsed. its the entire floor board front and back i didnt even run the car so its not the ac drain. Any idea what it is?

You may end up having to take all the carpet out to get it dry and also to be able to see water coming in that normally hides under the carpet and the mat that's under it. That avoids mold if you can actually air dry them on the garage floor, e.g..
Take out rear seat bench to see if you have water under there that's migrating.
Look in trunk and check the wheel humps for leaks that lets water thrown by rear wheels get into the car.
Check the front floor board for leaks coming from HVAC box from where it gets air from the cowl air intake and drains down on front floor below firewall.
Check for leak around windshield.
Sunroof? Check for leaks for the two front drains that go through the floor at bottom of the A-pillars.
Rear drain tubes can also uncouple and leak.
A side note is that the sealing caulk on a few seams in the body under the cowl intake leaked on earlier cars. So it was a matter of resealing. On some Cobalt/HHR bodies, there was a square that sealed an access hole and that could end up leaking water into the HVAC box area.

Sometimes spreading down newspaper in the interior and then working the car over with a garden hose can reveal the source of entry.
If any work has been done inside the doors, power windows, power door locks, etc., you may have a bad seal on the water shield that deflects the water back to certain drain holes and to the outside of the door to drain through the holes on the bottom edge. (Are those holes open? Or blocked by tree debris?)
Another has been drains for sunroof that come down through the A-pillar and then through the floor. Sometimes they've become disconnected close to the floor penetration and the sunroof water goes inside the car.
If these "easy" diagnoses fail, then take off the cowl and look for penetration there around seals or caulk that have let go.
Extreme examples are the wheel well in the trunk having a crack in it that let water that was slung by the tire get into the trunk and go forward on the floor. Or into the wheel well--have you checked in it for water?
Again newspaper shows water really great. I'd paper the inside of the trunk with it. TAke out the rear seat bottom and put paper there. Under the door edges. Even under the dash up against the firewall on top of the carpet.
As for suing GM, if I were defending such a case I'd point out that immediate remediation by seeking a professional shop should have been done to prevent aging of the problem and mold occurring.
If you've got a garden hose and a sunroof..., you can have someone run water slowly into the corners and you can lie on the ground to see if you do get drainage out of each of the 4 corners (I assume all sunroofs use 4 drains).
