Pretty old thread; but last year I was offered a trade for an electric Metro for my City-el. No thanks, plug-n-go- I don't know. Just last week I saw that same Metro in Craigslist with an 'as-is, doesn't move' warning about motor to axle connection grinding out.
There must be an EV God
! City-el is way over-amped, is about 77 pounds over the limit, exceeds top speed and acceleration- so has less range, very tricky charging; but took it out yesterday on highway 1 (in-town) with no problem.
