People don't buy these things "hoping" for things to fail. Complexity of the new era automobiles makes that inevitable. Would you say all the new Mazda engine improvements via new technology (turbo engines with cracked blocks, oils leaks, coolant leaks, CD problems) contributes to something that will be around a long time?Yes I agree, if you purchase an extended warranty or service contract hoping for enough things to fail to make the cost of the warranty worth it, you are much, much better off putting that money aside instead.
It also amazes me how many people get upset when they don't get to use their extended warranty.
It's a gamble either way nowadays. You have to gauge what you're willing to spend or not spend.
I've only bought 2 extended warranties out of the last 6 new vehicles that I've bought. I'm nearing the end of my current EW and will be using it before it's up (heated seats no longer work, timing cover leaking AGAIN, belt tensioner leaking AGAIN which was also covered by the EW the last time it was replaced). All this on a vehicle with only 72k miles on it. It gets used hard.
To each his own.
