When I picked up my F15 X5 last year (July/2020)...I knew that it had the option that should include the cargo net. When I went to take it for a test drive...I took a peek after opening the left cargo panel...and sure enough...there was the brand new net still in its little plastic bag...never opened, never used.
I also got another surprise...the box in the pic below was still in the cargo area...and brand new floor liners were installed (front/rear)...and a quick peek into the box revealed a set of 4 oe rubber floor mats...used but still in good shape. Then when I got home and pulled the rubber floor mats out to give them a good cleaning since I prefer them over the floor liners...the original carpeted mats were also inside the box still in their original plastic bag...never used.
