Don't have one to sell you but I've always looked for a single OEM driver's side floor mat on all my cars as they are first to wear out. No one sells a single mat at least as an OEM part...always sold as a set.
Your best bet is to check eBay or other sites. I snagged an OEM set last year on eBay when people were upgrading their floor mats to winter floor protectors and liners instead of original carpeted mats. Some people don't want to keep two sets and will sell the OEM ones.
