Shhh. They probably don't know. If they did, it would be priced higher.
On the E46, getting an Individual leather interior meant you usually got the steering wheel in two-tone. Extended was an additional option. Usually this gives you the lower dash and center console, as well as door inserts but I've never seen the seat backs done in leather as well. This thing's sticker must've been crazy high vs. similar optioned non-Individual E46 M3s.
