I am looking at this car on Craigslist, it is a 2017 30kWh with 96k miles, the owner claims it has 10 bars, but didn't include a picture in the CL post. is it realistic that it still has 10 bars after that many miles?
10 bars sounds reasonable to me for this car. The battery warranty will run out at 100k miles so you'll be on your own but if it really has 10 bars at this point I'd expect it to continue on for some time.
It's worth it if you want an EV today and it meets your mileage requirements and the price is reasonable. Also, do you have a place to charge it?
Here's a great post with lots of information: https://www.mynissanleaf.com/viewtopic.php?t=26662
