Before my mg4, I'd never driven an EV , I was not able to test drive one either ( I need adaptions to any car to drive it) but I would say it's the best car I've had. My old Fabia vRS had awful throttle lag, a reoccurring battery drain issue and an always present whirring noise in the cabin. the plastics were easily scratched and ugly, as was the seat fabric.
The mg4 is better in every way conceivable, it's vastly cheaper to run even with my limited mileage, is comfortable and easy to drive and has enough poke throw you back in your seat should you wish.
I've been getting around 230 per full charge (trophy long range) and that'll cost me around £10.
As has been stated before, lemons of any brand exist ( my vRS is one such car I feel)
But as long as you keep in mind it's a budget car and don't compare it to a higher end brand like BMW, it honestly isn't bad value for money.
