Besides the stains, it's too thread bare in a couple places. IT's not a matter of cleaning it better or dying it. I see more than you do in the photos. It's a gonner.
I'm not doing this because I want to "restore" the car; I want to "fix" it.

PS: I DO appreciate everyone's suggestions about how to try and save it. But no matter what I did, that carpet would end up 10 times worse than anything else in the interior.
