Did that come with the car, or did you pay extra for that? Mine came with all the floor mats, but my cargo area doesn't have a removable carpet (except for the plastic bin cover)
Where did you buy your Prius v Three Soylent? I ask because I'm looking at my sticker of a Three bought in NC and distributed by Southeast Toyota Distributors, LLC and it includes as distributor installed options (and you can't get one in AL, Fl, GA, NC and SC from any dealer in those states without em): AAUS2 USB Charger and cable BP Bumper Protector FP5 SET Distributor Plus Package PV4 Carpet Mats TWAS7 Legal Window Tint for AL, Fl, GA, NC and SC This mandatory package of options cost $816.98 on my sticker and the carpets IIRC were front seat (2), rear seat and trunk. I later added WeatherTech mats for all three areas. But the point is if you are in FL, you should have received the same package. Did yours get the security cover bar that mounts at seatback height and accordions out to cover the stuff in the trunk?
I do have the retractable cover bar, but no cargo mat. But i also did not get a USB charger and cable (just a USB port) or a bumper guard. I'll contact the dealer and ask if it is supposed to come with the car or not!
Then Tank your posting in a Prius v forum has led us to give you advice that, while well meant, is not on target. The v is the "station wagon" and may have very different accessories and distributor installed "options".
The problem with flipping it over is the rear cargo mat isn't symmetrical so it fits annoyingly when flipped. Otherwise, it would've been a good solution.
Many posts that end up in the Prius v areas (esp. from those w/low post counts) usually draw suspicion from me.
