I've had a read through all your responses. Thank you so much for the help. Really inspiring to see an active community like this.
- Mountain mode. Awesome! Didn't know it had that, so I'm glad I asked.
- "Thinking man's car"... you don't know how much I see that as a plus

- Leg room. Thanks for your insights. Obviously I'll need a testdrive to tell for sure, but now I know its worthwhile arranging said test. Sounds like it will be fine.
- Cargo. Amazing that I can't find seats down specs. My Fit, for example, is 20.4 cubic feet up and 57.3 down. Its right there in print. I don't know why I can't find that about the Volt. I was starting to wonder if they folded down at all.
- Kid in the back. This still seems like the X factor. I appreciate your attempts at answering, but again... test drive will tell.
You folks are right that we'll outgrow the car. That's inevitable as my son gets bigger. And probably sooner than is convenient (we typically keep a car 7 to 10 years). But I'm committed to driving an EV and I'll put personal comfort on a backburner for that. At the moment, I don't believe there are any EVs that suit our needs for the future other than the Model X - which is just too much $. I hesitate with the Volt because it isn't a pure EV, which is primarily why I've always dismissed it. I figured that if I'm going EV, I may as well do away entirely with the gasser. But there's no non-Tesla EV that works for us as our primary vehicle in this are due to lack of charging infrastructure. For long distance travel, really it is Tesla or bust at the moment. For that reason, the Bolt is out.
The Volt (electric only) meets 90% of our needs and its gas extender makes the other 10% possible. Every short range EV meets our needs for the same 90% but fails completely at the 10%. Long range EVs of course still meet the 90%, but for the 10% its either a minor inconvenience with a Tesla, or a significant challenge otherwise. Actually where I said 10%, I meant 9%. Then there's the 1% where I go north... maybe 1 trip every 5 years or so... no EV can go there. But then for that we'll either keep the Honda (probably not) or rent something.
I said the Bolt is "out", but that's not a final decision. I'll take another closer look at charging to see if it would meet our 9% - in case things have changed. But then... there's the matter of availability, which is worse than the Volt. I've been told I can't have one until 2019 here - but that was by a dealership that I had to convince (and this is just this past May) that it even existed. They kept insisting I meant Volt with a V (*sigh*).
Again, I appreciate the insights. I'll arrange for a testdrive when I visit vancouver on the weekend of the 11th and I'll go from there.
