Hello- I'm looking to get into my first Range Rover Sport, have up to £20k to spend, and only do up to 5,000 miles per annum. I'm tempted by the performance and character of a Supercharged 4.2 litre petrol HSE or HST - but am somewhat conscious of not 'wasting' my hard-earned cash on fuel. Whilst frugal, the 2.7 diesel looks mind-numbingly dull. What would you do?
