Yeah, Tesla has mobile service but the real issue with a used one is all the dumb little failures on things that should just work. It’s clear they cut corners on basic car stuff like windows, AC, and trim (friends of mine in engineering there there confirm this).
Example: they literally used Home Depot floorboard trim on early Model Y to mount the heat pump. You feel the bad design when fast charging even in a MY2024, it vibrates through the floorboards. I’ve never had that happen in any other EV.
By contrast, my Lightning hasn’t needed service at all.
