I would also recommend looking at the price-steps:
1st) 3 yr / 36,000 miles - the initial price drop trigger
2nd) 60,000 miles - drive train
3d) 8/100,000 miles - hybrid parts, battery and inverter
It is not just the year but also the miles versus the residual warranty
value. But so far, I'm not seeing a problem.
In 2005, I bought a 2003 with 49,300 miles for $7, it was $k under
KBB. I still have that Prius with ~120,000 miles and am still getting
But as others have pointed out, one really needs to do a differences
test by examining same year and miles non-hybrids to see what their
residual value has fallen to.
