I think I paid 600 for 42 month extended warranty, so 500 for 5 years is a good deal compared to what I paid. The warranty has no miliage limit and no deductible which is very nice. I am pretty sure it covers everything stock that fails due to manufacturers defects. As long as it is not obviously your fault they should cover it. That comes out to less than 28 cents a day for the 5 year duration, and thats pretty cheap for peace of mind.
