I mean simple math... the most cost efficient option is and always will be a 2 year old Toyota Corolla... if you are not doing that, then you are not using the most cost efficient option.
However, I will argue a Tesla model 3 is by nature a fast car so that doesn't make it comparable even if you discount the electric drivetrain.
A fair comparo for a base model 3 MAY be a Camry Hybrid which again isn't exactly comparable but still holds a near 10K price advantage...
The model 3 is a good option if you want to explore EVs but it holds no true cost advantage no matter what blabber anyone tells you.
