I picked up this mat as an extra; was going to use it to "sandwich" some sound deadening material underneath my mat. If you are making your own you may want to try that first, rather than purchasing. The mat is in fair condition at best, it would require some cleaning, but it is structurally sound. I am not sure what I would charge for the piece, surprised that it is so expensive as there is not much to it. I have fabricated some pieces for my vehicle and would be happy to help you save some $$$ with a few suggestions. How are you planning to make the mat?
