Y'all have a cute community here around a very cute little EV! Would love some pre-purchase advice.
A friend has offered to sell us his 2012 i-MiEV (SE?) with 29,000 miles on it. Sounds like they have cared for the battery well (running it down to ~25% before charging, not letting it sit too long, not sure about fully charging or not though). I took it to a neighborhood mechanic who hooked up his computer to it and gave me the codes that it read. p1a15 was one among a few. He also called the local Mitsubishi dealer who quoted him $12,000 on a new battery pack

Car seems to drive great. Powers on every time, and still has close to 60 mile range.
We don't have the facilities to do repairs / tinker if it starts to give us trouble.
Any thoughts on what a fair price would be / if this is even a smart purchase?
It's fun to drive and I'm shocked at how little juice it takes and how many miles it can go off a charge.
Thanks!!
