And carefully looking over these prices, it's good to remember that there were battery issues with early Leafs in some locations. Of course, it's also good to remember that the battery is under warranty for up to 150,000 miles (just 100,000 miles in some states), so check the odometer before you buy. A quick look at those cheap Leafs on eBay shows that they commonly have between 20,000 and 30,000 miles on them, so you should be covered there. Of course, you won't be able to take any sort of federal tax credit for these used EVs, but you're already getting a good deal on what what the future of the automobile just a few years ago.
It's not that Nissan doesn't stand behind its early EVs (or, really, all of them). Aside from the warranty, Nissan added the Leaf to it certified pre-owned vehicle program back in 2013. If you don't like the idea of eBay and want to get a used Leaf direct from Nissan, then you can easily find one there, too for well under $10,000. Some are even under $9,000. The problem with searching for a Leaf this way is that you need to enter a zip code that actually has a Leaf for sale in it, otherwise the dropdown menu will not even give you the option to go looking for Leafs. That's a problem that Nissan should fix.
One last thing about those sub-$10,000 Leafs. A year ago, finding a Leaf for four digits was a rare thing indeed, but Leafs tend to depreciate rapidly. If nine or ten large is too much for you now, just wait another year or two. Gas prices will still likely be low then, but going electric isn't just about ignoring the gas station. It's about changing something that used to not be changeable. And now you can do it for a lot less than it used to cost.
