Like I said multiple times now.... you can literally buy any part the car is made up of on the used market. Anything. The false narrative is that Tesla won't sell you parts and you can't get them anywhere so if something breaks you're screwed. That's simply not how it works.
That's IF you buy new and IF you buy from a dealer and IF you pay their absurd rate for the maintenance. It's a sales tactic. It's not an unlimited manufacturer's powertrain warranty which is what we're talking about here. That also stays with the original purchaser of the vehicle.
All new Teslas came with an 8 year unlimited mile powertrain warranty that follows the car to every owner for free. That's easily the most comprehensive warranty in the biz from ANY automobile manufacturer. Don't believe me? Here's a list:
Click me. You'll see that Tesla is the ONLY one on that list that's unlimited powertrain warranty and there's a reason for that. The other best options are only 100k miles with most coming in at the 50-60k range. ICE vehicles will have more problems because they're not as reliable so if manufacturers tried to warranty them with unlimited miles for 8 years for whoever owned the car they'd be bankrupt after about 6 years. That alone should be enough proof of how much more reliable EVs are long term. Hell, the Volt was the most reliable car GM ever made.
