That's good going! I think anything above 40 is a bonus to be honest with you..
Sounds mint, when I drive to Bristol i sit at around 68 most of the way (280 miles) and usually get around 40 which im buzzing with haha
Yeah that’s decent for saying you don‘t buy these cars for the mpg.. Personally when I’ve got a long motorway journey I stick it in eco mode and try and coast off the gas as much as possible. Doesn‘t feel as painful when you drive like a lunatic then
