Why replace the entire battery pack with a new one?  Why not just
replace the individual bad cells?  Why not get a used battery pack
from a junkyard (wrecked vehicle)?   Most used 2001-2003 Prius battery
packs tend to sell in the $00 range.

Or, you could live in a CA emissions state like I do (MA).  Warranty
on the 2004 and newer Prius' hybrid battery pack is extended to
10 years/150,000 miles, instead of the federal warranty of 8 years/100,000 miles.

Breaks should last forever too.

I don't think there is a real price to "replace" the battery.  Yes,
you may find costs, but my understanding is that the battery is
modular, and only the bad modules need to be replaced. Since you don't
necessarily replace an entire battery, the cost would depend on how
many modules get replaced.

 We are working on the assumption that the batteries will HAVE to fail. There
are no moving parts in the battery system. Lead-acid batteries have an
infinite charge / discharge cycle life, especially with computer control of
the process. If a company warantees an item for 10 years / 100000 miles (12
years / 120000 in CA Emission states) then it is safe to say the useful life
is at least twice that. As mentioned in other posts on this thread, there
will be other things that will fail much sooner, and most people don't drive
vehicles into the ground. Car manufacturers count on replacement cycles of
40 months or less, so for the vast majority of owners this wouldn't even be
an issue.
