Maybe a little off subject, but might I suggest looking at the Husky Xact-contour fit liners instead of the weathertech. I had weathertech in the past and swore by them, even bought them as gift for family-I liked them so much. But the last set that I bought for the raptor, just never quite fit right-especially the passenger front. I also got a little sick of the hard hard plastic feel of them (I like to drive barefoot sometimes.
Saw some reviews on the Husky Xact-contour liners and people were raving about them. I cought a 20% off sale on auto anything (weathertech was excluded from the sale) and thought I'd give them a try! I FREAKIN LOVE THEM. The fit is amazing and they have a softer feel but are still very durable.
One thing I would say is to still get the weathertech for the back seat area. I've heard the fit isn't perfect for the second rows. Also got the Husky's for the wife's SUV front seats but still the weathertech for the cargo area in the back. Heard the same things about an imperfect fit for the back.
For the front 2 seats...I don't think you can do better than getting the Husky Xact-contour (or maybe it's called Xact-fit...something with Xact in the name).
