It could be multiple things

1. Sunroof drain is blocked
2. Bad windshield seal
3. Bad door weather stripping/seal
4 Door is may have shifted and is letting water through (this is what happened to me and I had to reposition the door)

I dealt with it when I bought the car about 4 years ago...only had minor surface rust.

I would start by checking all 4 door seals. If there is not a gap or a small piece in the bottom section, they have shrunk as all do and allowing water to run in around it.

Start by removing or loosening the trim in the door sills.
Pull the seal off the car starting at the corner by the dash and pull if off all the way to the sill trim.
Now with it hanging, start putting the seal back on closest to the dash and make sure it is pressed on fully.
When you get to the upper rear corner, pull up a little slack from the floor. You should have about a 2 inch gap at the bottom.
Finish pressing the seal back on and make sure it gets into the corners nice and tight.
Adjust any slack back to the sill and replace any trim or hardware removed.
If desired, you can get a small piece and cut it to fit in the gap or leave the gap there.

If needed, I can add pictures to each step to aid in this task.
