So, what you're saying is that there's really nothing mechanically wrong with the 2002 IDrive other than the critics not liking the system? That's crazy!
With regards to the setting config, I think I've seen that Mini BAR configuration in one of those actors 745! It could also be that in the 4 seating config, they use the middle part to drop down so that you could put in your Skis or golf bag with clubs like they have on my 740.
On the 645ci, I don't what is, but everytime I see it parked, I'll do a double take and drool over it....it's like seing a beautiful woman that stops you dead on your tracks and then stare and ogle! Grrrrrrrrrrrr!
