I'm looking to purchase an 05 FEH w/ 75k miles, and look forward to keeping it for awhile. But on these hybrids, what is the life-expectancy of the gas and hybrid components?

I have a 96 Accord with 220k miles and an 02 diesel Excursion with 210k miles and they are both still SOLID vehicles. They are maintained well as would the FEH be, but being new to hybrid vehicles, I'm just concerned...

If I'm not mistaken, Honda warranties their battery system for 10 yrs. What is Fords warranty? and does anyone have any input on aftermarket hybrid warranties?
