24 KWH batteries come in a least 3 versions, one of which can generally exceed the manufacturer warranty (60K mi.).
Ah, good. And the second version is the one I have, has an SOH of 89% as of today, and 43,861 miles. I don't think I'll have any problem exceeding 100k miles and 10 years. In a favorable climate, of course.

For the 30KWH battery, the latest firmware update seems to fix the warranty issue for Nissan. Nobody has reported any actual increase in range that I know of (and I have asked the question on the forum). The question of what was actually fixed is quite up in the air right now. If the firmware actually fixes a miscalculated SOH then the 30KWH battery will be on par with the 24 KWH ones which still won't be that good. It might push the failure range out to 6 years and 75K mi.
Actually you might actually want to actually read the actual test report...

Once the correction was applied, there was a close match between the energy stored in the battery as measured on the dynamometer and the energy reported by the car’s LBC, for all seven vehicles with firmware 4A. We therefore conclude that the recently available update is a genuine and accurate fix to the reporting problem identified in FTF’s March 2018 report. One can think of this correction as an improvement in the accuracy of the car’s fuel gauge, including a recalibration of how big the “tank” a Leaf has when fully charged, and the way this degrades as the car gets older.
With the warranty at 8 years or 100,000 miles, you then predict that almost all of the 30kWh batteries will be replaced under warranty even with the firmware update. So do explain how this "seems to fix the warranty issue"?

If MSRP isn't relevant, then how about average selling price before incentives? Oh yeah, remember to add in depreciation when you calculate that TCO.
Depreciation? Haven't owned the car for 10 years, so I have not yet a clue. No one has owned a LEAF long enough, yet. Assume zero value in 10 years, and I'm likely still below average TCO, assuming that repairs and maintenance stay realistic.
