Classic need for a diesel. An X Type is the same as you've got in a Saville Row suit that will get ruined doing 50k miles a year. An A4 is less reliable and belt cam with the same sartorial problem. What might be quite interesting is a Hyundai i30 1.6CRDI with balance of 5 year unlimited mileage warranty. You just have to think of a car the value of which you will destroy almost completely. So paying extra for flash is stupid. But you still have to live with the thing, so can't go too cheap and nasty.
