Sorry PHXGT and AZGT,
I didn't check the forum yesterday - out driving all day! :banana
The anchoring holes are unneccessary and can hardly be seen once in the car. They were a surprise to me when I received the mats and I would order without if that was an option. When I ordered, I didn't see any mention of them as an option or not. The mats have a rubber backing and do not slip once installed. The fitment is quite good. They conform slightly to the underlying "rubber mat" of the floor and are thick enough and stiff enough to smooth out the floor quite a bit. It makes the car a tad bit more comfortable. The front flap on the passenger side mat folds up over the fuse box and fits quite well. I do not see the need for two pieces at this location. My only criticism is that not all blacks are created equal. In certain light, the black of the mats is slightly different than the rest of the black in the interior. I have had this criticism on just about every set of black mats I have owned regardless of price. The factory black mats in my 997 which cost almost twice as much have the same issue. That being said, I would order again, especially for the $$.
