...$3.25 per ...?

Totally bogus of course. I can operate my TCH for a lot less than that even with a reserve fund for battery replacement.

Six year life fully amortized to $0 at 20K miles per year.

Indirect Operating Costs:
Acquisition cost: 32K or about 26.6 cents/mile
Insurance: 1400/year or about 7 cents/mile
Licensing (Good in WA) $68/yr or .lt. 1 cent/mile
Battery Reserve ($3800/120K or about 3.2 cents/mile

Direct Operating Costs:
Fuel $3.50/gal @ 40 MPG (conserviative for me) or about 8.8 cents/mile
Service, incl. minor consumables Avg $200 @ 5K intervals = 4 cents/mile
Service, Major Consumables (Timing Belts, Tires, etc.) 6 cents per mile

Does not include garage or cleaning as I would need to do that for any car.

All of which gives approximately 56.6 cents per mile, even with the battery overhaul reserve and/or a battery pack swapout at 80Kmiles. I have tracked the costs from purchase, and so far I see no reason to change this model.

It is the ignorant among us that will eventually destroy us all.
