I noticed on the passenger side, where the seam in the floor meets the door sill, it tends to have a little dip or low spot in it that's about a foot long. It then levels out as it moves into the foot well. My son rode in that seat a couple of days ago with wet boots and I noticed today that there was still water that had pooled up in that low spot. Is that low spot normal? Comparatively, it's pretty level on the driver's side and near both rear doors. I don't mind wiping up the water but it seems like the floor should be a bit more level. Could water that collects there get under the flooring and create possible moisture problems - or does the flooring material overlap with the door sill somehow?
