I had one as a company car for about 2 months and couldn't wait to hand it back.
Very nice to drive and quick aswell but to get any sensible range out of it you had to drive it in eco mode. My drive to work is 21 miles a mixture of a and b roads and driven sensibly in the flow of traffic it would get me home aswell. I think the best I got on a full charge driving with slippers on was 87 miles before the display was warning me that I would soon be walking.
If you charge it with the box of tricks it comes with and using an extension lead make sure you fully un roll the lead or it will double up as a torch with added smoke ,speaking from experience there
I certainly wouldn't buy one with my own money.
