Hi Brydo,
I would think easily with the seats down to fit a wheelchair, the boot is golf size some models have a variable floor in the boot also.
As for home charging it’s been a doddle, I am going to rock the boat here, but I had BP Pulse install my charger, no drama’s and all done within 3 weeks of the application going in. So my experience has been positive.
I moved to an Ev electricity deal with OVO, 15pkw anytime of the day or night. Optimum charging is to 80% of the battery, takes about 3 hours to charge from 20 to 80%, giving me around 170 range which is adequate for work and pottering around. Cost wise around £3 per charge. I would only charge to 100% if going on a long run.
