While I don't see it happening, I'd appreciate a cut-rate deal from Nissan on a replacement battery pack (ideally with 30+ kWh). That would enable us to use the LEAF a lot more.
The "trouble" is, our LEAF is only missing two capacity bars (though it seems pretty close to dropping a third bar), but its reduced range and crippled regen make it impractical for a good fraction of our routine driving. So it stays in our cool mountain environment and is used only for shorter drives (virtually no trips off the mountain, just used within our local mountain communities). As a result, the battery capacity is dropping at a very slow rate; it's possible that it will be missing only three capacity bars when it reaches eight years old. Admittedly, it's been a couple of years since I've bothered taking it down the mountain for a battery check.
Part of our issue is that the 24 kWh pack was sort of marginal for us from the beginning. But in early 2011, the 24 kWh LEAF was the only "mass market" EV with room for five people, so we did our best to make it work for quite a while.
Buying a used Tesla last year was helpful to me in recalibrating my expectations for our aging, greatly-depreciated LEAF. Now that we have an EV with lots of range and Supercharging, the LEAF is filling the role of a "second car" pretty well. Sure, it won't go far, but it's pretty low maintenance and it has more value to us than it would have on the used car market.
2011 LEAF at 69K miles, pre-owned 2012 Tesla S 85 at 89K miles
LEAF battery: 9/12 bars and < 49 Ah (-28% vs. new)
Tesla battery: 250+ miles of range (-5% vs. new)
