The present invention provides a pair of consumer cut-to-fit car mats manufacturer which are not merely mirror images of each other
. Each mat has a central area of a body surrounded by a plurality of peripheral cells which are separated from the central area and from each other by elongate indented trim lines. The consumer may select any of these cells to be trimmed off of the mat or to remain with the mat as trimmed. The number, position and shape of these cells and trim lines is quite different from one mat of the pair to the other, as are the outer margins of the untrimmed bodies.
