I’ve circled the area in yellow

No, i my Felicia was ''empty'' so i grab the chance and installed noise insulation sheets.

You can also cover it with self-adhesive gray carpet.

Good idea D!

I saw a reply from Lee01 which said ‘yes’.

Lee01, could you post a pic, or a p/no?

I was pretty sure there is a panel - it's been a while since I looked in the boot of a Felly. Also logically, why wouldn't they cover the rest of the cargo area and there's what appears to be holes on the upper edge for trim clips and in your pic, there appears to be a left over trim clip, top left corner of your yellow line. You've also a vertical piece missing on the right of the pic.

Τhe holes are for the clips of the Ω shape plastic panel that is missing, in the centre there are two metal columns like I I shape,this is the main support for this part.

The whole area is covered by factory carpet and behind it are the cables for the rear lights, the wire for the trunk latch.

To save money. I own a 2005 Seat Cordoba, which, compared to earlier models, is missing cover on the bottom of the dashboard. It wasn't visible, unless you got your head into footwell, so they replaced it by much smaller piece of plastic that only covered the visible part of the area.

Similarly, top of the cargo area has no trim, even though rest of the trim suggests that at some point, it was planned (or maybe present in higher trims, who knows).

This part of the boot floor is similar case, it's just not part that's not visible under normal circumstances.

Thanks, makes sense. As I said, it's been a while since I saw the boot of a Felicia (2009). I was weighing up a Felicia but then a very good and cheap MkI Fabia caught my eye.
@Papez I had a MkI 1998 Seat Toledo. 64bhp diesel. Slow as hell but reliable.

Even aftermarket trunk covers have that _Π_ shape to fit left-right on the I I shape of the body metal.
