looks yellow, guess it doesnt matter that much since the mats cover it up. i tried cleaning it with some carpet cleaner, still pretty bad, my floor mats are all hard and flakey... probably common problem im guessing. any way to clean this better?

Took 3 application and a lot of scrubbing but it did the trick.

I used one on my 5000 once, its dark interior but wow was it dirty water that came out of the cleaner. im thinking this carpet stuff i used (which smells like ****) is just too weak, thanks for the tip now that my car reaks ill have to do that asap! :)
