Not many A2 TDi's for less than £3500. real world MPG, you can get 60 + mpg but on a daily basis 56 is about the normal. this goes down in the winter if you allow the webasto heater to run which keeps the engine warm. 75 TDi's only have a 34 ltr fuel tank so you are forever filling it up if you do a few miles a week Tax is £30 a year
