Well, it says 64KWh in MG's own literature, so I used that figure, just as I used the 65mpg Yaris figure, despite legions of users and reviews saying higher.It is 61kWh usable battery on the MG4, so slightly cheaper than you state.
As you say, they are different classes of vehicle, so this is apples and oranges. A motorbike with sidecar would be far cheaper for us to run, but we are in the market for a family car.
It baffles me sometimes why it is all about cost when people are forking out £30k+ for a brand new car. Saving the pennies is best done by running old cars into the ground.
Agreed different classes of vehicles, but both you and I are not the only people on planet Earth. Apples and oranges, but Bob is the buyer and is deciding which one to buy. He might like an apple and he might like an orange, but he might decide that the taste of rising electric car ownership is now getting a little granny (charger) smith-like in its bitterness.
That is true about saving pennies after spending ~ £30K.
But countering this ~ 90% of new/nearly new buyers buy on finance, so won't be forking out £30+; they'll be getting a finance company to buy it and then they'll pay a monthly amount for 3 or so years.
