I recently redid my car cost/mile spreadsheet. Since it's a long way to town, it's important to know how much each trip costs.

I've left all non-mileage-related costs (DMV, insurance) off this calculation.

I made the assumption that I would drive this car x number of miles and drop it off at the dump, so depreciation is simply the original cost / x.

The other assumption is that I'd spend about 12K on repairs/maintenance during the life of the car. Judging from the car's first 120K miles, that's way high, but as it gets older it's going to need more work.

The result for my Echo is 20 cents per mile. Can you think of anything that I forgot?
