It is a mixed bag. Early model S cars are only 8-9 years old right now. Still pretty young to determine true long term reliability. Tesla also kept the reputation decent early on by offering warranty repairs on pretty much everything. I've heard it is not uncommon when looking at an 2012 model S to have reports of 10+ door handle replacements. The real test will come at the EOL time for batteries. If it is similar to hybrids, that comes at ~15 years. I imagine in ~2027 virtually all original model S cars will be in junk yards/salvage auctions when they are totaled by a dead battery.

There’s no parts supply or third party sources of most components, so I’d guess that you’ll have cars off the road for stupid part failures before the drivetrain is caput.

Yep , Tesla’s aging is quite good any gas car after 100k miles don’t drive like a new car. Tesla 100k is totally fine .
