I'll agree with part of this post. The WeatherTech mats DO work well for capturing wet stuff, but where they excel IMHO is with catching dirt. They seem to be coated in some sort of sticky/staticky compound which holds dry stuff very well. The downside is that they can be a b1tch to get completely clean, but it's a small price to pay.
I'll have to disagree with the price however. I paid $38 for a complete set of OEM mats for our Isuzu Axiom, and they fit, look, and perform incredibly well. When I had my Infiniti G35 coupe, I bought a complete set for $75, which is even more impressive when you consider that almost anything costs more for a luxury vehicle. Believe me when I say you can get poorly fitted mats that perform just as well for much less.
