I agree that Weathertech all-weather mats are great. In my current SUV, I have the digital fit mats for the front and second row. For the cargo area, I just have their cargo mats. Their digital fit mats have a super high lip (around 4 inches high) vs most all-weather mats that go up maybe a half inch (if that).

I'm definitely going to order the Weathertech's for my new X5 once I get it.
