I would suggest checking out a couple of other threads.
This one has info and pictures of floor mats:

This one has part numbers for mats, liners, etc. Realize, there is a difference between the floor MATS and the floor LINERS. Take a look at each and decide which one you want. Generally, the floor liners rise up higher around the edges - probably better if you live in a wet or snowy climate. The mats don't rise as high on the edges - probably good enough if you live in a warm or moderate climate like southern California.
