At an average 14K miles per year and a guessed 25 mpg, that’s 560 gallons/year. At $4/gallon (guessed and well over the US average), that’s $2240/yr.
If you exclusively charged with completely free electricity and still managed to drive that 14K miles in a year, you’d save $187/mo.
If it moved you from 25mpg to 40mpge, it’d save you a little over $70/mo.
Our two cars are a BEV and a hybrid, so I’m no battery-hater, but neither is cheaper than a reasonable gas-only equivalent would be.
that is a large pile of money saved there, but not as much as payments.
Still cars don't last forever - my pervious minivan needed a transmission rebuild so we can cut the cost of the replacement by 10000 since either way that money is spent and now the newer van is break even on payments and it should still work after it is paid off for a few years.
