Guys, if you remove your middle 2nd row seat, not only must you put the bolts back in the holes, there is also an EXTRA hole plugged by the seat that is open to the outside world once the seat is removed. This must be plugged as well or it will let in fumes and vermin. Trust me, I learned about this the hard way!
BTW, one of the nicest things about the Platinum model is the leather on the seats. It's a "premium" leather which I believe is the same as what was used on the Navigator. It definitely feels more plush and comfortable than the leather that comes in the Limited and loaded XLT models. The KR leather is probably thicker and it has a different feel. I'd consider it more "heavy duty." But, the Platinum leather feels truly luxurious to me.
