My guess they'll reside round the Med and possibly California/Middle-East ... in the hands of owners with a stable of cars to profile in at will, with no need to take it out to the shops on a wet Wednesday.
So much has changed but I remember that you needed some way of looking backwards ... if you had an interior mirror then no need for wing-mirrors or vece-versa.... it could always have a discrete rear camera setup so as not to spoil the profile. Most owners will have three Escalades filled with boduguards and personal-assistants in convoy behind them so no need for looking back 🙂
