82 miles is sufficient. Keep in mind EV's at the moment are mainly intended for use within your own city or just about anywhere you won't be stranded and always have range or some sort to charge it.
I see Spark EV's being used a lot in busy cities as commuter cars so in that case 82 miles is more than enough, great if you want to run some errands after work before heading home.
From what i've seen a good number of parkades have a few parking spots with EV charging units, anywhere outside of a busy city...GOOD LUCK. Even in some suburbs you might be SOL.
