Thanks gentleman, that is helpful indeed.Leo excuse my ignorance what are def issues? Is that filters? I did here low mileage around only towns may not suit. However fuel economy is worse, do you know what auto petrol versions are best rated? Again I am not interested in high speeds etc.... must be getting old! I can take time for the right car but know little about XF petrols. Any thought...... Also i guess you can get low co2 models?
thank you both
