2018 Model 3 Performance for $16,000?

It has 127,000 miles, but looks brand new. Test drove it and it was just like any other Tesla. I’m apprehensive about the battery being out of warranty. I’ve heard battery issues usually manifest early on and it has another 200k on it, others say it could go tomorrow. I really just want a cheap on of these as a second car to beat on. I don’t qualify for the EV used tax credit, but my mom does - so that might be an option. Thoughts?
