So based on fuel alone the payback would 4000/1270 = 3.2 years and that is without taking into account maintenance savings i.e. no oil change, brakes last forever, many fewer moving parts to wear out etc.
Nice reply to the earlier question. I have done the same math on my Focus Electric and have derived the same result.. After less than 3 years, because I commute 20K per year, I will be saving substantial money on the car.
Add to that the fun of driving a little speedster and
the joy of not purchasing gasoline and
the satisfaction of "Putting my money where my mouth is" when I talk about reducing greenhouse gases and
the cool electronics like SYNC and myFordMobile. Can you tell - I am so pleased with this automobile?
Enjoy your ride...
