Just got my cargo mats. 2 pieces, one for main cargo area, one for when the seats are down. It is a flexible clear plastic that fits exactly. VEry nice company to deal with. If you are interested, ask for Billy Husbands, 888-395-6004.
Unfortunately, I am still in the dark ages and dont have a digital camera. If I get around to it in the next few weeks and people are really hot on seeing them, I will make the effort. The mats are very similar to a clear plastic chair mat I bought in staples. A clear plastic mat with rows of little plastic points on the underside to keep the mat from moving around on the carpet. Cost is a little pricey, but you may be able to work with him on that. He quotes $100 for both pieces. They are an exact fit and the seat down cargo piece has 3 cutout openings for the raised boxes meant for the carseats.
