Came across this link when browsing another forum and thought some of you may like to know about it (if you don't already!)...
Interestingly, there are prices for retrofitting many items that are not shown otherwise (laser lights, TV modules, driving assistant, boot liners, etc...)
Hope it is of use, you'd have to start from the top level directory and then choose the right car but nevertheless hope it is of use.
