Personally I've wanted a Volt for the past 3 years. However, I really am the kind of person that doesn't like to upgrade unless necessary. It's been instilled in me since I've been a kid. I've had my current car (Kia Rio) since December 2005 and it hasn't let me down yet.
The things I am weighing are:
Do I really need an extra expense right now? No, especially if I am moving to California soon. Not having a car payment is really nice.
How will this Volt save me money on gas mileage? Quite a bit, since I don't go places very often and work from home
Do I *really* care about the environment and getting off old dinosaur bones to fuel my car? Yes, I do. But if the energy I'm using the charge my vehicle is coming from those sources anyway then this may be a wash..I'd have to investigate the power sources for where I'd be moving.
Will it handle distance driving since I like to travel? Yes, since the gas generator backup kicks in after ~38 miles. And the generator is actually quite efficient and gives better MPG than most combustion engines anyway.
When I do move to California I will likely drive whatever vehicle I own. I've driven my Kia across country twice and it would definitely survive a 3rd trip. I don't think I'd want to add the 1500 miles to a brand new car.
And lastly, the predictions for the 2018 model haven't really impressed me that much. The one feature I loved is when they found a way to reduce the battery size and fit a full back "couch" seat in the car. This is super necessary for me, who travels with my dogs a lot. They did that back in 2015.
But it's kinda my dream car. Gives me the ease of mind of using electric nearly 90% of the time, and a nice backup gas-generated buffer to "go the distance".
