I went to Walmart and bought a set of Super heavy duty rubber ones. They have the deep channels perfect for holding rain/snow. I used the smaller ones that normally go on the rear floor, and set them ontop of the engine shelf. The passenger one fits great, and I had to cut the section away that would cover the brake and gas pedal. I was able to cut it and leave the "flap" on the left side to run up where my foot rests. The mats have a Honeycomb pattern which fits the yellow/black smart I have. As a bonus, I used the cut away section as a liner for my storage pockets on each side of the steering column.

For the 2 mats up front and the 2 small ones in back acting like a tray-came to $26.00
