When i bought mine 4 months ago,the computer showed the previous owner averaged 21.5 mpg. I have averaged 22.7 in the last 4 months with a mix of town and dual carraigeway driving,taking it relatively easy and i rarely floor it...Bmw quote combined at 22 mpg iirc
There is no way you will get some of the figures mentioned here unless you do 99% motorway driving at 70mph,i have taken it really easy on one tank and the best i got is 25mpg, driving like a pensioner.
