I recently needed the rear trunk carpet inserts for the three compartments in the rear of the C5 Corvette. It's a single piece of molded carpet that inserts into the rear of the trunk. From Chevrolet, the cost is $475, if you can find a dealer that still has one in stock as it looks like it's not being manufactured anymore. To the rescue came https://www.VetteNuts.net, an online used Corvette parts seller. They had a used piece in stock for $49. It arrived via Priority Mail 3 days after ordering and it basically looked brand new. Below are pictures of the carpet and before and after shots.

I recommend this place if you are looking for replacement parts for your C5 or your C6.
