Has the decline in demand for large luxury saloons plateaued? If it's the USA we're talking about, then the answer is no, with the S-Class (6,155, -27%) and LS (2,697, -38%) still falling. Yet business is good in China, with retail sales of the Audi A8 numbering 6,288 in H1 (compared to just 1,330 in the US) and the BMW 7 Series seemingly holding up well on 9,653 units. The arrival of an updated '7 couldn't come at a better time.
