Why?
I will likely stand out as the peckerhead in this thread, but here goes anyway:
An extended warranty program is a for-profit endeavor on part of the issuing party. There are tons of exclusions, such as wear and tear parts and abuse, to name a couple.
Odds are not in your favor that you will collect more from the policy than you spend on it.
The car has a Toyota powertrain...doesn't get any more reliable than that.
I understand that many people perceive value in extended warranties, but I just don't get it (actually, I do...

).
