What 83-240d said is right. There are drain holes through the rear of the sunroof but if those are clogged they will mostly likley create water draining into the back seat. As far as the floor on the drivers side im pretty sure this is caused by a clogged drain that comes from the ac. Ive never experienced the problem myself but have heard of it and it is supposedley easy to fix although im not sure exactly where its located. Im sure someone will post a follow up to clear that issue up.

On a side note, everyone just needs to chill. no one needs to post to tell someone how rude they are. Its all good guys, we are all just here to help and be helped. Just keep it cool.
