Having picked up my car on the 1st March I've just come back from a weekend away in North Wales giving the car a good shakedown and I too am so impressed at the MPG!
70.5mpg on the motorway and then average across the almost 400 mile trip of 65.6mpg, which considering a large percentage of it was on the coastal, mountain and country B roads is fantastic!
Loving filling her up too, I filled up yesterday in Porthmadog, spent the day driving around Snowdonia National Park and then drove back to Warwickshire and this morning it only cost me £18 to top it back up to full tank....I could get used to this!!
Totally agree jonnyg30, it doesn't take long for the needle to drop though, but it definitely takes longer to drop all the way to the bottom!
So my official review after 700 miles of driving in a week - absolutely loving it!!
