Sadly I would need a couple of USB sockets in the rear should I choose to go with the car, but no big deal as I could install a couple from the 12v boot socket. Alternativaly a long lead can be taken tidely from the front for those with less knwow how.
I’m going to have another look at the Kona when I’m feeling a bit better, to check out rear passenger and boot space and look at the possibility of a roof box, although using one would affect the mileage no doubt.
