You're better fixed than most people as far as the cost of setting up your charging station. It sounds as though your usage is very similar to ours: my wife's car is pretty much short runs around town and the boys use it when they are home from school. My truck is our usual long-haul vehilc. An EV would probably be a great replacement for my wife's car, except.... her BMW is in a very similar circumstance as your car: it's a '17 with quite low mileage and paid for. In today's market, especially, it makes more sense for us to continue to drive our 5 year old vehicles.
