Both M.B. and B.M.W. have gone so much overboard in the electronic gadget and gizmos department (maybe to try to keep their up-market appeal) that to me both marques are now as unrealiable as your next door Lada.
A friend of mine bought one of the early new 7-series, and he regrets it every day and night.
As they have done most early W220 owners.
