It is designed for comfortable, refined travel rather than city-centre parking, and competes with executive flagships such as the Mercedes-Benz S-Class and Audi A8. Its understated styling gives it presence without being flashy. mycarcheck.com has recorded 136 look-ups covering 58 different VINs, a useful sample of interest in this version.

The 3.0-litre diesel suits long-distance commuting and business travel, while the automatic gearbox and cabin make it relaxing for drivers carrying passengers. It is less suited to tight streets or buyers seeking low running costs: this is a premium car to maintain. Compared with rivals, the 730d blends comfort, performance and diesel economy.
