This option is a rip-off from the factory, & a MAJOR rip-off from Ford parts. It would not have cost Ford any more to make all the plastic inserts hollowed out like the "cargo management" option, probably cheaper because less plastic required. GM offers an under floor compartment as standard on their Lambda crossovers, along with a cover for the upper rear compartment. The Edge/MKX has no hidden or out of the way storage without paying extra, & if you didn't get it from the factory it's BIG BUCKS extra for two pieces of cheap plastic.
