This is the thought behind why we took the plunge and stretched ourselves out for one when we needed a van.
Throw Canada's (at least Ontario's) higher fuel prices in the mix with our time-of-use charging rates and our ROI was not as far out in the future as I had expected before running the numbers. We had bought when the provincial EV rebates existed, but before the federal rebates existed, so the ROI would be a longer now than it was when we bought.
BUT... We're still very happy.
Our usage pattern for the van plays into it's capabilities very well. Still have half a tank of gas, last fill-up in April.
Winter fuel use is always a bit of a shock after going through warmer months so easily, but even then it does just as good on gas as our other smaller vehicle.
