We have a MHEV 1.0L petrol auto. I wouldn’t pay more for a mild hybrid as you don’t really save anything and this was the best auto estate option at the time. It’s a nice drive and achieves 40/50 round town and 60+ on a long run.
But as others have said, if the car you want is available in full EV at a price you are comfortable with, I’d definitely go for it!
