I am quite new to the forum and to the X5 altogether. I purchased it for the wife but I find it more fun to add to than my car. Anyway, I have seen some pics where it appears to be a painted area on the back diffuser area where there is not one on my 2006 X5 30i. I have added the titanium grill, the front spoiler (painted), and new OEM floor mats, and OEM all weather mats, with the OEM rear cargo liner. I really like the look of the rear painted area, I just wasn't sure if it is an option I can add. Thanks in advance.... Jamie
