I am about to be a brand new tc owner, though I haven't actually got my hands on the car just yet. The one I'm getting also had this problem when I first looked at it. There's 21k miles on it so hopefully this hasn't been an issue for too long. The dealership that had it was an Acura dealer that didn't say anything about it. But the evidence of a leak was apparent upon noticing the wet carpet in the floor pans. This was made worse by the plastic that they put over the carpet to keep it clear. It just held the moisture in even some mold had started growing on the carpet. (This is in New Jersey and mold grows all too easily). They didn't want to do anything about this issue but I got them to drop the price down instead. I picked up a new set of the seals, rather than re-gluing, though perhaps that would have been the better option. I'm also thinking that I need to pull up the carpet and get rid of the jute that is under there since it is probably molding now. Check and repair for any rust that has taken a foothold.
