There are so many variables with real life fuel consumption though. Some time ago I remember top/fifth gear trying to evaluate if the low rolling resistance tyres actually improved fuel economy and when they were testing it started to rain and they found that the rain had a greater impact on fuel economy than the tyres. Personally I think unless your fuel economy is completely untenable you have to live with it.
As a side issue my father-in-law was considering swapping his 07 plate panda for an eco-panda. Apparently it would do 6 mpg more. We worked out on his mileage (minimal) the advantage would be £41 per annum - including the saving on road tax. Not worth it.
