I guess car choice and calculation behind it is very individual. I never wanted Tesla, but got best trade—in conditions there.
I am saving a bit on repairs as well. I was spending close to $1500 a year on maintenance for the old car (but it was 8 years old and had 100K miles on it). We also had a nice tax incentive for buying EVs/PHEVs, so that helps.
Gas at the closest station to my house is currently at $3.40 (according to Google Maps)
EDIT: I don't see anywhere on my bill that I'm paying a peak rate. I do charge my car at night though, so I wouldn't be surprised if I'm paying the electric company extra just to do that.
It's the medium distance trips that are more annoying. On a 400 mile trip you'd normally just drive that straight. Adding 20 minutes for a charge is sometimes annoying.
I'm not complaining too much since I plan to keep this car until the wheels fall off anyways, but it does seem like the accelerated depreciation of EVs versus gasoline cars is a good reason not to buy at the moment.
EDIT: I should clarify, my vehicle is a PHEV. I couldn't commit to giving up gasoline given the added convenience of being able to quickly fill up on gas for long road trips. That being said, I drive less than 10K miles a year and probably only use ~1 tank of gas every 2 months.
