You can usually find a cargo area mat available from AutoAnything.com or AutoSportCatalog.com.
Here's a link to a cargo mat available from LLoyd's via AutoAnything.com:
Crossfire Coupe Cargo Mat. You'll need to adjust for year & model.
Most folks get the custom LLoyd's mats (cargo & front pair) that CICCI setup for the Crossfire. You can check that out on the CICCI website.
