I test drove a Leaf on Sunday (with my boys in the backseat). It was pretty cool! I didn't take it very far but wow what a smooth quiet ride. The boys loved it too. Sadly it was all I heard about for the rest of the afternoon.
I could see myself driving one of these things to Hamilton, but somewhere like doing a loop of the Coromandel would be a little bit more challenging - charging stations seem to be few and far between there (as far as I can tell).
