While driving back along the M40 last night in my E63 i spent sixty miles driving at a nice steady 60-70mph. Managed almost 30mpg over the journey - the best consumption figure ive had with this car. Stopped at a services to fill up and took a pic of the special moment! I'm not sure whether this is an achievement or a mark of shame driving a car like this like an old codger. I did get overtaken by a Polo a one point but at least it does show you can get a reasonable MPG figure if you take it easy.
