Like others, I buy new so I know it's been maintained, I take care of them so they take care of me, and I keep them a long time--mainly because I hate the car buying experience. I've had several Dodge/Plymouth minivans all go over 200+ miles (I replaced the oil pan gasket on my 2002 and the internals were spotless). I've had mostly Subarus and Mopars and all have been great--my 2014 Ram 1500 diesel has over 125K miles and the original brakes and battery and very few issues.
My youngest on the other hand, has silhouettes on his own car of his last three kills:
--1991 Firebird--he never checked the oil, it broke down and after pulling the dipstick, it came out clean. I had some used oil I hadn't dropped off, and thinking, "what the heck," I put it in the Firebird gave it a jump and he drove it another year
--1998 626 (240+miles, had the original clutch when it passed), the radiator blew and then the head gasket went because he didn't shut it down; warping the aluminum head. I gave him the caravan and drove the 626 (no white smoke, just combustion gases in the coolant system) a few months until it finally lost all compression
-- 2002 Grand Caravan -- after 240K miles, it was still going, but he beat the living snot out of it and used it as a trade in on a newer used car that he mostly keeps up the maintenance on
