American car brands traditionally did not last 100k miles until the Japanese brands flooded the American markets in the 1980s.

There are performance automobiles, though, (Porsche, Nissan) that don't use hydraulic lifters in their "consumer" vehicles and require valve adjustment at 100k miles.

200k miles is actually a pretty big deal still, as it's about the lifetime of efficiency valve stem seals, crank bearings, and catalytic converters, and self tensioning timing chains.

20 years is also the upper limit on rubber and plastics; so if a car is 20 years old and hasn't had all of its suspension bushings, hoses, and seals replaced, they need to be on the list.

Then you have the Ford Ecoboost head gasket issues and Chevy collapsible lifter failures which have led to less than 100k mile life of engines in the last decade on about 10% of their cars.
