Do you have to choose between these two?
I Took a gamble and bought the non ST Fiesta Hatchback cargo liner by weathertech, and dropped the floor. The mat is a tight fit but works great, even fills out those damn useless side pockets. As in the liner goes into them too, I removed the cardboard dinky dividers, very happy with my choice. Photos tomorrow if you wish.
If not, the fiesta one, simply because of the lowered floor. Why waist that 6 more inches of cargo room?
