And diesel cars like yours are THE reason why these type of legislation is being put into place. Your 2001 diesel is most likely a euro 3 emission type and that put on average 3x more NOx and 10x as much diesel particulate matter in the air per km driven than a 2010 euro 5 diesel (1). Of course you can do a calculation on how it is economically better to drive a car for a longer period of time compared to factories using resources to make new cars. But at this moment all the focus is to get NOx and particulate matter emissions down, preferably in cities. So noone, except you, cares about how fuel efficient your old car is because even the biggest modern Mercedes, BMW or Audi luxury barge is more environmentally friendly than yours. Buy any modern (less than 5 years old) normal everyday car and immediately you lower the amount the amount you pollute in your everyday driving. 1: http://ecoscore.be/nl/legislation/european http://ecoscore.be/nl/legislation/european
