I just found this very same cargo cover available at Chrysler Parts
use part number 82208889 in the catalog search bar.
They claim it's available in different shades.
Their price is $271.04 U.S. plus shipping.
Even at this price I'm not sure that I want to pay that much money for something that is retractable material and would probably hold up as well as the fabric sun shades (magic shade) used to prtect the dash when I park the car out doors, that need replacing every couple of years.
I would love it if I could find an actual cargo shelf for my XF.
