I’m retired, my mileage is only 5000-6000 per year and am considering buying a Jaguar XF. I wondered if you would advise the diesel or petrol version, as I vaguely remember you saying (ages ago) that diesel wasn’t best for low mileage. I’ve also acquired five grandchildren recently and, what with the teeth-loosening potholes round my way and the occasional need for 4WD, I’ve even considered an automatic 4WD Nissan Qashqai which can convert to seven seats.
