I picked this up with some other parts locally, I have not seen it mentioned here at all. It is shown in a catalogue of Crossfire options that I have but cannot find.
It is very handy and I use it to keep a folding box in position in the trunk. The four corner blocks have Velcroİ on the bottom and attach to the surface of the carpeted tray.
Under the tray is the OEM trunk mat, under that is a spare set of OEM interior mats and under those mats is a another spare OEM trunk mat which has never been used and possibly been there since two trunk mats were installed by mistake, who knows?
There is a Chrysler tote that was offered separately to go with this option and is offered for other vehicles as well. the mat fits the Crossfire trunk very well and was obviously made for it. The carpet has a raised lip all the way round the edge, maybe 1/2” high.

 

I bought a new Tiguan in 2018 and a new Atlas in 2019 and they both came with those corners and floor mats that they stick to. I bought an extra set of the corners on Amazon. They are pretty dandy for keeping groceries and stuff from sliding around.

 

That trunk mat with the Chrysler logo is unusual. I have an 2005 SRT6 and had a 2007 Coupe and both trunk mats are/were plain. The velcro plastic does not appear to be a Crossfire option, based on the information I had when I bought my roadster new. It looks aftermarket for any car.

I have a set of rubber winter mats that came in the 2007, oem bras and a wind deflector for my roadster. I also picked up extra luggage about a decade ago when some guy in Indiana bought out the remaining stock and then sold them online at a very good price. I ended up with two "n/a" sets and one SRT6 set. My next door neighbor has a Crossfire fitted car cover - I'm jealous.

 

I have a Mopar accessories brochure in a PDF file format and it lists the parts available for cars of that year and previous years. I cannot post it for some reason, it’s for the year 2007. I can assure you it is for the Crossfire and it fits like a glove, the mat and the corner blocks came as a set. Underneath it is the OEM mat and other some other spare mats as mentioned. The brochure shows it in the Crossfire trunk. There are two options for a Holdall for it, I have neither.
I have the SRT OEM fitted cover and I had the same for my NA but sold it. I also sold the OEM bra for the SRT as I do not like them, I had the NA luggage which I sold and now just have the SRT luggage. As you can see the mat and Velcro corner blocks are OEM articles. I have the OEM lighted mirrors and luggage cover which was one of the last six in NA when I purchased it, I kick myself that I did not buy the lighted sills when I had the chance. I had another luggage cover at one time but swapped it for a Canadian ICM (light switch) when I got the SRT.

Hi Goldwing.
I found a place that makes the floor mats. I bought a set and they are high quality. You can customize the colour and logo for the stitching .

PS. Do you have a Goldwing too? Mine is a 2003.

 

Lloyd Mats has a good selection of Crossfire mats with & without logos.

I have added the 2007 MOPAR accessories booklet in the PDF format in post #4 for those who wish to know what accessories were available for the Crossfire at one time.
I have all sorts of stuff on the computer about and for the Crossfire, digging it up is the trouble.
As you can see the trunk tray and Velcro corners were not aftermarket. I just got the chance to buy them quite cheaply at one time.
