I have one, you will seriously enjoy it, lots of toys and quick enough to make you grin, it’s also comfortable and quiet, with a cracking sound system. It is slightly small in the rear and the boot, however I’ve got a 9 year old and a 14 year old who fit just fine and it takes a load of shopping just fine.
I would say do your research on the car and EV driving habits/tips, spend some time learning about regeneration braking and such, plus the specific features of the Kona.
Enjoy your car
