Got mine today, both the 32 and the 48 oz.
Both are cut the same with rubbery backing so they don't slip.
The 48oz are really plush, but make it very difficult to pull the lever to move the seat forward and back, not that I ever need to move the seat.
The passenger mat is extra wide and curls a bit at the edge. I was about to be pissed and call them when I noticed a note on the mat explaining that this was by design for the passenger side, for 'extra protection'. After pulling them out I noticed a scratch on the floor (wifes high heels) that this extra bit of mat would have prevented, so I guess it's all good.
The drivers side is a bit narrow at the back (toward the seat).
Over all I am happy with them. 48's are really plush, the 32's are what you'd expect them to be.
I'll try to up some pics later.
