The whole idea that high mileage is the worst thing regardless (or largely regardless) of maintenance—that cars have a lifespan depending on what they are, and that things are worth selling rather than fixing—can get old. Cars are made of parts. Parts break. And unless the frame suddenly splits (which does not tend to happen), the car will go for as long as you refresh/maintain parts. Thank you for tuning into this public service announcement.

tl;dr meticulous maintenance>low miles when limited-lifespan parts have reached their age limits.
