I don't get what's the big deal over this 25th anniversary edition. I don't see any performance difference between this special edition and the regular V12 760li. So a few extra fancy gadgets and some extra nice leather and those buyers are suckered into saying: "Oooohhh wow, a big fancy "V12 25th anniversary edition" label all over a 760li, I gotta have that!"
If BMW wanted a special edition deserving of it's name, it should not have limited itself to minor cosmetic touches and instead really add to the area where it counts, namely the horsepower of the engine (and maybe tuning the suspension as well!).
Maybe it makes business sense for BMW, but it doesn't do anything for me as a BMW buyer.
