I ordered the Cargo Magic product from Mopar (through my dealer) and received it yesterday. It's really quite nice.
It's specifically designed to fit the trunk area of the Crossfire Coupe. A heavy-duty plastic-backed carpet tray has a raised edge to keep fluids from spilling onto the original interior. A Chrysler logo is embroidered into the mat. Four velcro-based plastic corners can be placed in any desired configuration on the mat to keep items from sliding around.
Mopar Part #82207797 Dark Slate Gray, with Chrysler logo, includes four adjustable/removable Cargo-Loks: $105.00
