If there is one thing I know about cars is that do not buy if you cannot afford to fuel it. With the ever rising fuel prices one does not even need to drive on a full tank, just know your mileage-fuel calculations and you are good to go.
However when you drive a range rover there should be no excuses. Running out of fuel should be the least of your worries. Refuelling a Range Rover with a Jerry can is an injustice to such a magnificent creation of man.
The owner of this range for example should just sell it and opt for something that is not a fuel guzzler. Like a tuk tuk.
