My 04' 6s has some pretty bad carpet. Wasnt great when I bought it a few years ago, and my kids havent helped. In the past, I did a roll on bed liner on an old blazer floor, worked great for my truck. Wondering if anyone has done this to their car. I figure I have 3 options. Shampoo it and hope for the best, replace it with carpet which would cost the most, or put a roll on bed liner down and make it indestructible.
