He's got 5 years and 100K on it, which he should *need* something....

FWIW, I got a warranty on my brand new X when the 4 was up.
I think I paid around 3400-3700.
Regardless, I used up at least 11K in repairs during the warranty.
It paid off for me, but like insc., it's a gamble.

Depends how well the adjuster/appraiser handles each claim as well...
