Intuitive to operate, excellent tactile feel, high seating position. More range or a larger battery would be desirable, but that would be nitpicking at the highest level.

Delightful driver's car. Light-footed, quick, silent and sporty.
If the range could be improved, it would be absolutely top.
You do have to buy a few option packs to make it fun — expect to pay around 70 grand.
