Some pictures would be great! I'm particularly interested in the difference in the height of the sidewall of the transmission hump on the driver's side -- it appears that is the major difference between the Weathertech and the BMW OEM. Well, that and the fact that the Weathertech 2nd row mat is a single piece that covers the center hump area, while the BMW OEM is two individual mats.

I'm leaning towards the Weathertech if it really does have higher sidewalls, but I am a bit reluctant to order from them. The owner does write a really good letter about buying American products and other "Down Home" things, but if you read their website they are rather vague about their return policy. And for good reason it seems. According to another poster, if Weathertech sends you a product that doesn't fit well due to their design, the return policy is that you pay postage to return it, you pay the postage that it took to send it to you, and then you also pay a 20% re-stocking fee. So if I bought a liner set and a cargo liner for roughly $300 and wanted to return it, I'd be out about $100 net if they didn't fit well.
