When I bought my Gen1 V10 it didn't have the cargo net but did have the storage under the seats which (I think) was part of the storage option with the net. My previous V8 Gen1 didn't have the net. However, the reason I mention this is that the V10 had the button mounting holes at each end of he carpeted shelf so the net clips into those button holes and the upper edge of the net clips into holes in the pillar.. Before you look for a net it's worth checking that you have those mounting points in your car. I liked the look of the net and also it's useful at times. I persuaded the dealer to throw the net in with the car deal. It's nice quality but it's crazy money for what it is.
You can see the buttons here....
