I'm not going to make you search.
You have a choice of going cheap or expensive. I'm going to lead
you down the expensive path.
As others have mentioned in this thread,
Weathertech is the most
durable floor mats you can get. The cost for 4 all-weather mats came to
about $150. Before you choke on your morning coffee over that price, you
need to realize that these are the best mats that you can buy from a company
that is renowned for its quality.
I have an ebony interior and these are the mats I purchased:

Some things to be aware of. These mats don't cover a small area --
they are custom fit to cover the entire interior carpet offering unparalleled
protection from water and dirt. Also, when looking at these and other
mats for an AWD vehicle, be aware that they need to be made specifically
for AWD as the drivetrain (if that is what it is called) is narrower than the
non-AWD CTS. You'll notice when shopping around popular online car
accessory specialists for mats that a notation will be made about which
CTS you want to buy the mats for.
Let us know how you make out.
