EV cars will save over $17,000 on fuel and maintenance costs for every 100,000 miles driven.
That is using today's* gasoline prices and regular maintenance costs at the dealer for a typical car sold in the USA -- that gets 22.5MPG. Maintenance is about 25% of that -- basic services every 5K, intermediate service every 15K and full service every 45K miles.
Do the math for 100K miles: fuel costs are average MPG (~22.5 in the USA?). So, 100,000 / 22.4 = 4,444 gallons X $3.729 = $16,573
The maintenance I went with typical dealer costs for basic maintenance every 5K miles, intermediate every 15K, and full maintenance every 30K. The numbers I used was $75 for basic, $200 for intermediate, and $500 for full.
That means there are 14 basic X $75 = $1,050
3 intermediate X $200 = $600
3 full X $500 = $1,500
Total for maintenance = $3,150
So, the cost of maintenance is a bit less than 20% roughly speaking, at today's gasoline prices.
Total cost to run an ICE car for 100K miles = $19,723.
Remember as well that the oil and other waste materials add to the carbon footprint of driving an ICE; as does the increasingly difficult to find oil to make gasoline.
Cost to run a Leaf the same 100K miles, using the EPA average of 340Wh/mile and off-peak charging around here of 8¢/kWh: 100,000 X 340 /1,000 = 34,000kWh X $0.08 = $2,720.
Cost to run a Fit EV the same 100K miles, using the EPA average of 290Wh/mile and off-peak charging around here of 8¢/kWh: 100,000 X 290 /1,000 = 29,000kWh X $0.08 = $2,320; or $400 less than the Leaf.
The Mitsubishi i MiEV is slightly more to run than the Fit EV, but slightly less than the Leaf.
Since there is virtually $0 for maintenance on an EV that you don't also have for an ICE, that means you save $17,003, which is much more than the cost of the Leaf battery *now*; let alone 8-12 years in the future.
This means the Leaf actually costs you $35,200 to $37,250 - $7,500 = $27,700 to $29,750 - $17,003 = $10,697 to $12,747 for the first 100K miles! Drive it for another 100K miles, and you come out "ahead".
Sign up for $0 down solar PV panels to be installed on your house, and you pay about HALF of what you do now for electricity AND save that $2,720 as well.

I think that a majority of the cells will last 200K miles and so the cost to replace them will be more than paid for in the savings. In fact, driving an EV is "free" when compared to the average gasoline car; if you drive it long enough.
