I would recommend you go to Wal Mart and purchase a nice set of bathroom rugs and cut them out and fit them accordingly front and back. Total cost would be $50 max. Beige is a light color and they will get dirty soon. I have beige and I chose a nice moca brown color. Really blends in well with the Wood trim.
You can even wash them in the washing machine. I even removed the plastic foot rest & cut a separate peice and stapled it to the carpet. Looks nice and all blends well.
Plus people love the feel in the summer when they have no shoes on. Not the driver (of course)
