Premium cars that aren't so premium as to be disposable (i.e. not a luxury car you're gonna trade in every 3-5yr like clockwork) always last really well because people who can afford nice things can generally afford to maintain them.

This is pretty clearly borne out when you compare same cars across brand e.g. Ford Lincoln Mercury panther platform cars) or look at the exceptions like all those objectively terrible northstar caddilacs and v12 Jags and whatnot that are in impeccable shape because they got used and maintained nicely for a decade before being "retired" to the garage of the owner's vacation property on Cape Cod or perhaps the Hamptons or compare airport people moving vans that were retired to church group service to work vans that got sold down the river to even harder service.

It's really easy to "well we really should sell a water pump while we're in here for your 100k timing service" on a Subaru owned by someone who can afford a Subaru vs selling a preventative transmission fluid change to the guy who could barely scrape together the down payment on a Sentra.

I'm being a little sloppy and leaving some loose ends and room for nitpicking jerks to wedge in but I think the point here is pretty clear.
