Yes, the Volt is a great (the best) gateway drug experience to go electric, Bugs. It really taught us what our actual needs were, the ins and outs of EV driving and what living with an EV is like (I have no idea what gas prices are anymore).
When the Bolt came out, I knew it would fit our needs especially regarding long commutes and winter driving miles. My wife's commute was 70 miles RT, so I thought of the Bolt as a 70 mile Volt with a 180 mile spare battery. With the new Bolt battery (February, due to the recall), we now get an estimated 300 to 330 mile range.
So yes, the Volt led us to replace our other car with the Bolt and the Bolt confirms that we can replace the Volt with an Equinox EV.
Funny thing is, all three are about the same price. The Volt was US$36,500 after tax credit, the Bolt was a little less than that with tax credit and GM discount dollars, and I expect the Equinox will be in the same general area after tax credit. But the Equinox will be a step up from the Volt it replaces. Hard to beat the current Bolt prices after tax credit though!
