I had them in my '04 and they worked fine. My Father has the McNeil mats in his '03 and the McNeil's definitely hold/trap more water than the Honda Factory rubber mats, due to the deeper groves. The reason I went with the factory mats is because the McNeil rear mat is 2 piece and left the center portion of the carpet exposed.
I currently have a set of the factory rubber mats in ivory on order....hopefully UPS drops them by today.
Also, they say that the rubber mats are not for use over the carpeted mats, but in my '04 they fit fine over them.... we'll see about the '06.
