Yeah, it’s a bit of a survivor ship bias, most of the cars from the 70s that are still surviving have even lower mileage on them. A lot of classic cars that are still around were ones that people put in barns after driving them 20k-30k miles. Most of the ones that were actually driven around and used died a long time ago.

A lot of those low milage classics are basically just show cars, where the owners cart them around in trailers so they can keep the milage low.
