The new vehicle hasn't arrived yet but is already having a domino effect of new purchases to be made. I found a cargo protector that should help keep the floor and seatbacks clean. Check out -

I've looked at many different options like the cargo trays and cargo liners. Online prices vary as do the many sizes, shapes and materials. This cargo protector is $75. on one site but only $60. at the above site. Rubber mats and cargo trays might be cumbersome to remove and put back in or not the right size. Also if you get the cargo tray that fits just in the 3rd row section, what do you do when you need to use the 2nd row too? I like this liner because you can protect the 2nd row seatbacks when they are up but have the protection if they are down. It should be easier to put in and take out plus it's washable. The width is a bit wider than needed so hoping the sides come up to protect those and not require cardboard. Oh, and don't forget the car air fresheners!
