Those 3D MAXpider floor mats look nice.
Another set I've seen that covers the hump in the rear floor is made by Findway.

I currently have the OEM all weather mats, and I kind of wish I had seen these two options prior to buying the set I already have. Even though I have a tan interior, another thing I would have done differently was to buy something in black instead of tan. Not only does it show less dirt, but I think black matches all colors pretty well.
If you get either product, please let us know and give a follow up review on it.
