Are we talking about saved money over EPA or over the vehicle it replaced?
It will take me a really long time and many, many gallons before Vera pays for herself if compared to the
previous vehicle, but I will get there eventually.
If we are talking about over EPA, then the car literally might not last that long before enough is replaced that it's even the same car. If that's the case then I should have named her
Car of Theseus.
