Anyone who has owned or seen an early `80's C3 with the "Silver Grey" interior option color (132 - leather, or 13C - cloth) knows that the carpet is more of a greyish blue color, with an emphasis on the light blue. It doesn't seem to be available in any of the C3 supplier partner's catalogs - all they seem to offer is the AC "silver" or "gray" with no options for a replacement color.
Has anyone on the forum with this vintage/interior color come up with a solution for this? I would like to replace it with the original `Silver Grey' color as the designers intended. Thanks in advance for any experienced insights.
