It's a weird time in the auto industry in general in terms of used car value my wife's old 2015 Chrysler minivan that we're selling to get a Y is worth around $5k more now than it was two years ago when we first looked at selling it.

But from what I've found, even separate from this current used car market Tesla cars hold value like crazy, since they don't have engines that die the way an internal combustion engine will along with all the over the air updates that keep it current.
