I have three children, aged between 10 and 13. I am thinking about buying a Ford S-Max as it seems spacious and provides more flexibility on seating than our current estate car. I would ideally like an automatic. However, I am concerned that most of the models are diesel. I use the car for stop/start city driving and only rarely do long journeys. I would really appreciate your advice on which model to go for, or whether there is an alternative I may have overlooked.
