My electrical usage/cost is so low that if you studied our home energy bills before and after we got the MiEV you could not detect the mont or year we purchased.
I calculated that for what it costs to buy a gallon of gas i drove about 330 miles. That's 330mpg practical equivalent out of pocket.
Then to be fair I tried to amortize in the cost of eventual battery replacement. Tough, because we can't know for sure how many miles or the replacement costs. But made middle assumptions and came up with about 90mpg practical equivalent.
(Since gas prices are down from when i did that calculation, today not quite that impressive.)
I've not spent a penny on maintenance.
Oh, wait....I did spend $5 on a can of fix-a-flat to keep in back, so in case if a flat my wife wouldn't have to dig under the seat for the OEM one.
BUT, I hate to admit it, but in ONE sense at least it has proven rather expensive to operate:
As a buyer rather than leaser, I like other buyers , have taken a huge hit on depreciation.
If i were to sell today, or if someone rear ended me (in which case if the battery pack got damaged the insurance company would declare it "totalled" and write me a check for about $9000) my per mile and per year ownership cost would be painfully high compared to, say, having purchased a Honda Fit ICE car.
I'll probably post more on this under a separate topic maybe titled "what would you buy TODAY."
Perhaps this depreciatin "hit" is moot in that we will likely keep this car for a long long time .......to the point where any car would have depreciated to almost nothing anyway.
