40 miles is about 10kWh, yes, which would be 11.5kWh at the meter. I pay 7cents/kWh, so you're paying about 10X per mile as I am for fuel. I've driven old BMW's, and I had to budget about $3k/year for maintenance & repairs, I imagine your Merc is similar. So you're spending $400/month for your "cheap" car.

A 3 year old Tesla for 20K would likely save you a considerable amount of money.

I do my own maintenance and repair and don't spend anything close to that (not counting my time, but it's a hobby for me). Insurance and registration is also cheaper.
