So far, but it is hard to find good EVs on the used market. Sometimes you can, but at the moment I'm looking and there just are not many options at all.
Is it? Will I be able to get parts for it 15 years from now? Will I be able to repair it myself? (I have rebuilt engines before, and I'm planning to replace the transmission in my truck myself this year, so DIY ability is important to me). There have been headlines recently about how unreliable Tesla is.
Transmissions on EVs are generally single stage speed reduction so yes in the extremely rare chance you need to repair it you can. The motors are way harder to repair but they're similarly way less likely to need repair. Other part availability will vary by brand just like with ICE cars/trucks there's nothing magically less available if we're looking at new parts, older common parts there's a bit of a difference just from the designs being newer so there's a smaller population of junked cars to pull random EV pumps off of the way you can with some old car parts.
It's the most popular vehicle in the world by most metrics, so I don't think you need to be concerned about parts. Especially if comparing to any other EV available in the US. Also extremely reliable. Don't trust clickbait headlines, look at consumer reports and satisfaction.
Might be location dependent I had a lot of options last time I was poking around when my current gas car started making potentially expensive sounding noises earlier this year. (they stopped so I'm fine again /s)
