most miles/Prius

But alas, Jesse got broadsided by a 17 yr old driver, and the 2002 was totaled at just shy of 350,000. He was OK, but the 2002 did not make it. It had the original battery and no major repairs to speak of. He's now working on a Gen II and by now should be close to 100,000.

 

Jesse's 326k was original in all the high-dollar parts. No wait I cannot say that for sure because I don't think we ever heard if he had the original steering.

He may well have done things like wheel bearings, struts, ball joints and the like.

I think we are still waiting for a Prius gas engine to wear out. There have been one or two engine replacements (at least), subsequent to total loss of engine oil. Things like a hole punched in the sump or the drain bolt left loose.

On the other extreme, there are a few who have paid the big bucks for batteries and or transaxles. Some of those got a cost-share with Toyota.

Those are the extremes. for the big bulge in the middle, best guess now is that you may be buying something in the log term, but that the overall costs will still be equal or less than a conventional car. Not a bad prospect overall.
