The Stealth trims are gone, Tesla just “does” stuff and if you can’t handle them changing stuff on the fly then maybe it’s not for you. On the plus side of changes we owners get all sorts of random updates and new *sugar* that BMW or Mercedes or Ford will never do and don’t want to.
Buy a used Stealth if you really want that trim but honestly any trim is great. There’s not much for incentives to buy new unless your state gives you something. Miles on an EV are not equivalent to a gas car so don’t be afraid of 15-20K miles on a 12month old car if you find that rare Stealth trim.
And really the paint and panel gaps are not that bad anymore, especially on the Model 3. Don’t give anymore attention to those old articles.
