I was wondering what mpg others are getting in their Cooper D? Mine is a 59 plate. It's reaching 12,000 miles now and i'm still only averaging 52mpg. I drive it so economically, always gentle with acceleration, braking etc. I always change gear when it tells me to, never go above 2000rpm, always in the highest gear possible. I use the stop/start when the weather is above 4 degrees! My journeys tend to be no more than half an hour each way which of course will drop the mpg, but to say it should reach 70mpg combined, i'm still way off
!! Over the year it hasn't nudged from 51-52pmg the whole time.
