Eh, people have lost much more money buying overpriced McMansions.
If you intend to own the car for a long time, it is less risky to buy a reliable brand new car than a used one of the same brand. Unless you know the owner.
Knowing the owner doesn't affect the rate of random failures in the middle of the bathtub curve. The only thing it gives you is maintenance data.
These days, it is extremely easy to get maintenance data for many late model used vehicles. Many manufacturer websites will spit out all of their maintenance records as soon as you register an account on their "owners" portal and put in a VIN.
You can get a good idea from maintenance records; hard driving wears consumables faster. Compare a few vehicles of the same model and it'll be easy to see which ones were driven harder.
The last car I bought had two original tires on it at 60k miles, and the service history showed the other two were replaced due to nails in the tread. I am confident the vehicle was not driven hard based on this.
