Yes, I pretty much concur with your experience Oscarmax, although the battery was empty at the start of my test drive so I didn’t see anything above 40mpg.
I couldn’t order one there and then, but I did go back a couple of weeks ago to place the order. Roll on May.
Just need to decide which charge point to get now. My dealer couldn’t offer any special deal with a particular supplier but said they normally recommend Rolec.
