If you work on the fully considered co2 value of a much newer petrol car that will achieve anything like the fuel/energy efficiency of an older tdi rather than just the exhaust emissions then you could build a case for a 10 year old diesel that costs £2k over a considerable more valuable car, which will then depreciare even more due to putting a high milage on it
But main argument is private hire /taxi that all run ancient idi diesels often in terrible mechanical condition chugging round city centres.
