Buy a Prius.
It's more to track the miles I do each year but thanks for the advice..
MOT does that.

I use my 2.5 auto for work and have an app to track journeys for tax reasons, and it has averaged 26.1mpg over the last 810 miles. I can drive on motorways, countryside or town, best tankful was 28mpg, worst 23mpg.

Trouble is, you cannot help sticking your foot down even if it is just for the sound of that engine, and the way it hustles around corners in the country, and the feeling of acceleration and power. If I wanted a car that is good on fuel I would not have got this car.

Hell, in 20 years time we will all be forced to use self drive electric cars, with petrol and diesel cars being limited to 500 miles a year on classic car status and fuel will cost £20,0000 a gallon, we will all be wishing we could go back to thrashing our cars around when it only cost a small amount more. I worked out that it costs me £200 more every 5000 miles to use my Z4 than it does my Santa Fe, which does 35mpg.
