I just made a
TCO spreadsheet in google documents that you can use to adjust the TCO numbers from the
Edmunds calculator.
You can weight each value and also add a constant to each one. Say, for example, that you think repair costs are too high in the Edmunds estimate. Well, you could multiply all its repair numbers by 0.5 and then add $200. Why you'd want that exactly is beyond me, but I wanted a balance between power and ease of use. You can also type in the miles per year you expect to drive. This only scales the fuel costs. Edmunds assumes 15,000 mi/yr in their TCO, FYI.
The spreadsheet is user editable, so you can enter the values you want. I have a few cars in there right now just as an example. Hope it's useful to some of you, although I realize it's still pretty crude and that having to enter the Edmunds data is annoying. Better than nothing! For some reason the cell comments only show up in the correct place when you go to edit it. They're piled on at the end like footnotes when just viewing.
Oh, yeah, I guess I should have a disclaimer or something:
This spreadsheet is available in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
I hate that crap.
This is my first google spreadsheet that was more than trivial (not to mention intended to be viewed by others), so let me know if it can be improved.
