Parkers overall rating: 4 out of 5 4.0

The cabin is plush and also very logical in the traditional manner that BMW is famous for. The materials used are top-notch, well-made and look like they will be durable. Entertainment and aircon systems are controlled by the BMW iDrive system (a dial on the centre console of the car). This allows the dash to be de-cluttered of buttons. A head-up display to aid the driver can be chosen as a cost option: it projects vehicle speed, navigation and vehicle warning lights in front of the driver and is a really useful tool.

With four different driving modes ranging from Eco-Pro to Sport+, the BMW 6-Series is trying to be everything for everybody. In fairness it does a convincing job, though we're not sure many will be able to detect the differences between Comfort and Comfort+. The 6-Series is very refined and cossets both driver and passengers as it glides you along on your journey.

There are a few downsides, however. Visibility is poor and it is hard to gauge the front (long bonnet) and rear (small screen) when parking. Keep your car free from scrapes by adding parking sensors is advisable because it's not the easiest to judge. The A-pillars are quite large and obscure the vision on tight bends.
