I remember I bought a Subaru about 10 years ago. The sales guy asked if I wanted to consider an extended warranty. I gave a clear, "No". I was expecting a long-drawn out pushback. Instead he responded with, "Yeah, that's why you're buying a Subaru, right? Because they are ultra reliable!"
So isn't part of the reason you are buying a C14 is because they are known to be ultra reliable?
Beyond that, I don't really believe in warranties. The business case for warranties and insurance are the same: They have to take in more money than they expect to pay out. I have to buy insurance. Anyways, the buyer is betting they are going to draw the rare straw where the price of the repairs are more than the cost of the insurance. For every person that says, "Thank god I bought the warranty for $1,000... the repairs would have cost me $3,000!" there's going to be many folks that don't use the warranty at all, or at least for repairs that cost less than the cost of the warranty.
I would roll the dice, put the $1,000 in a separate account, and ride.
Just my $0.02
