we have a 2003 Chrysler concord after pulling the carpet out we sat inside while someone ran a hose on the outside. in less then 30 seconds we had water rolling in about 8 inches from the front of the drivers side door on the bottom . we took the three seals out of the door and windshield and found there was no sealant applied at all from the factory. after cleaning and using some sealer from the anybody shop there was no more leak. i would say the 300M is the same way after seeing all the complaint on the internet about the same wet drivers side floor board. we are going to take the passenger side seals all apart and seal them as well. I hope this is helpful for anyone else having this problem I would of saved a lot of money if i would of did this first. Don't take it to the dealer cause you will pay for not getting it fixed.
