My mother has a 2006 Ford Five Hundred with 156K now. She got it at 60K in 2011 and sort of overpaid for it at a dealer, but honestly it's been crazily reliable thus far. A lot more problem free than our old 2001 Taurus, actually. We got it in 2005 or 2006 I believe, so about the same age and mileage. That generation of Taurus was basically rental car grade. We had an alternator and belts go, thermostat, stop leak in it for a coolant leak somewhere, the shocks were all screwed up and both rear shocks broke springs and had the back end sag and a spring stab a tire. AC filled with stop leak goo, too. Tranny felt like it was slipping at times, hard shifting. I wrecked it at 19 with I believe about 130K.
By comparison, the Five Hundred had some Lucas PS fluid thrown in and semi-flushed out, one set of plugs and coils done at 150K, and one drive by wire throttle body going on it. Bushing for the top motor mount is going (the one connecting to the strut bar.) AC compressor needed a new check valve, too (easy repair, only $30 compared to a new compressor.) CVT still shifts great, want to do the fluid when it warms up. Overall a substantially better and more reliable vehicle, weirdly it's mostly Volvo engineered, though. Needs new shocks and one control arm bushing because terrible CT roads, but at least the springs themselves aren't broken like the Taurus.
I will say, the highest mileage car I've seen in real life was my father's 2006 Ford Freestar with 450K on it. He went through two transmissions and it was ran ragged, but he ran it on Rotella 15w40 diesel oil until the very end. He drove it to the junkyard.
I used to kind of disrespect Ford, but now I think they're the best of the domestic companies. But apparently the very newest cars are disasters.
One thing that made me respect Ford too was Ford has a decent presence in Asia. There's a lot of Fords in Taiwan, for example.
