Prius is a tough case:
On the plus side, you really only use your drive train a portion of the time; and even though the very expensive batteries were only guaranteed ten years, most have lasted considerably longer.
But on the down side, while so much attention has been placed on the $3,000 batteries, nearly every g-ddamned thing on the entire g-ddamned car costs $3,000 to replace. I gotta keep feeding my 2002 Prius brake fluid because a small problem with the brakes is $3,000.
Still, 16 years and only two minor, but very expensive problems with easy workarounds (the other is the A/C, which keeps shutting off automatically because of another $3,000 problem)... not bad! But one day, a REAL major problem with happen, and oh, well.
Verdict: The car may last fifteen, twenty years before its first MAJOR service, but once it starts going, fuggeddaboutit; the car will be crap.
So, If you drive a LOT in a given year, get a Prius; it can do 30,000 miles a year as smoothly as other cars do 15,000 a year. So ten years, 300,000 miles is very possible. But at 10,000 miles a year, no, you won’t see 25 years, 250,000 miles.
Thanks, that’s useful info.
