Codex,
BMW Individual doesn't have option numbers. Yes, you can get a LOT of options (I think I could choose more than 100; check a European BMW site, such as the British one) but Individual means that you can go to your dealer with a colour stale or some kind of material for a seat and they'll make it for you. Options are almost unlimited this way. They offered me a brochure with a couple of examples, and yes it's very individual, most of the time very nice and always expensive!
