It wasn't that big a jump, because the Golf was a GTi with a DSG. The DSG gives a fairly similar drive to the EV setup. The MG4 isn't quite as quick off the mark for overtaking as the GTi was, but it doesn't have the hesitation/lag at the beginning of the acceleration so there probably isn't much to choose. I'm currently revelling in the smooth ride and the incredible road-holding. And the quietness.
I'm just getting to grips with the whole charging business. In particular whether I should bother charging overnight if I'm only down to say 80%, and not anticipating using the car much the next day. I think the answer is coming out at yes. Last week I had to rescue a friend who had had a catastrophic puncture, and go fetch the other friend she was supposed to be meeting, and then ferry the punctured one back to her car to meet the RAC guy. All totally unexpected. I was fine for charge, but if I'd begun the day at 100% I'd have had more leeway. We live and learn. (At least mine is an SR, so it likes being kept at 100%.)
