Mercedes E220d Estate

If you wake up in Basingstoke and have to be on the Isle of Mull in time to grab supper from the (Prince Charles-approved) fish ‘n’ chip van on Tobermory harbour, you need a car like this. A vast diesel tank means you stop more regularly to refuel occupants than the car and its blend of space, comfort, security, performance and useful tech make it perfect for a 556-mile trek.
