Depends on the type of car, the type of miles, and the type of driver....But yeah, a regular car with a regular use case*? I wouldn't really be trying to sell it at 40K either. I mean, I think some Americans (and no, again, not meant condescendingly at all) go a bit overboard in how long to make a car last (400+K miles on a gas engine? Yikes), but 40K is just about ready for a first check-up or something.
*the patrol cars used by 20+ different security agents rushing around from Urgent Intervention to Urgent Intervention all night without regards to mechanics; taxis; rental cars, driving off road in cars not meant for it, using a Kia Picanto to haul heavy loads up mountain hills,...all good reasons to replace a car earlier
