I would not recommend the diesel at all if you are a city driver. On my first diesel S type (2006 model) The DPF filter was a problem for all of the 5 years that I had the car and at 120,000 miles it just started to mechanically disintegrate, got rid sadly. Have had the petrol S type sport for the last year and it is way better than the diesel. No comparison. More cost of fuel but better in every other way.
