Compared to the cost of buying the car, or hell, the cost a few months of gasoline, installing a charger at home is a nothingburger. A one-time investment that immediately pays dividends.

It might cost $300 to $600 to put in a charger at home if all of the wiring is ready to go. That's small compared to the cost of buying a new car, but it's certainly not nothing compared to a few months of gas.
