The idea is that repairability and reliability are sometimes at odds.
I owned a number of 90s trucks and though it was easier to get into the engine, I had to do it well before 100k miles sometimes. Meanwhile I have a 2010s Japanese vehicle that is at 200k with only an alternator replaced.
Similarly there's now a few models of EV known to make it well past the 100k mark while needing little to no maintenance aside from replacing consumables. Most people aren't knowledgeable or well-equipped enough to work on those, though.
