I think Rory this is where you compare one with another that are not like for like.I also think the MPG difference is overstated in the real world - sure, my C270CDi auto can show 50MPG on the trip meter on a long steady run (which is the car's main use) but in normal urban driving it struggles to do 40 and around town it does 30. My solution is that I generally drive our Jazz - I hardly use the Merc. Jazz does 50MPG without thinking about it.
And the whole discussion is a comparison of diesel and petrol so we do need to compare like with like if we want any valid conclusions.
