Standard equipment is very generous. Entry-level Sport models have 18in alloy wheels, leather seats (heated in the front), a powered bootlid, adaptive cruise control, dual-zone climate control and even electric sunblinds for the rear windows.

This 3.0-litre V6 diesel is smooth and quiet, if not quite as refined as the 400d engine in the rival Mercedes S Class. It isn't as powerful as that engine, either, although performance is more than adequate and there's a healthy swell of acceleration available from low revs.
