Here's one more comparison for the group. I decide to buy the Weathertech HP mats. Online pictures weren't great, and it was hard to determine if the HP were the same or a different cut than the regular Weathertech mats. I emailed Weathertech, and they said they were the same.
So I bought the HP models and while I loved the material, I was a bit disappointed with the coverage. I decided to gamble and order the regular Weathertechs, and found they are MUCH better. They cover a lot more area, come up higher, etc. I very quickly returned the HPs. Here are 3 posts for the group, with pictures.
This post, I've attached the two mats, side-by-side. (the HP mat has the black label, while the regular Weathertech has the red/silver)
