Geez, once you've made up your mind about something, there's no changing it, is there? Lol. I explained my stance on warranties; they make sense to me. If they don't make sense to you, that's fine, but don't tell me I'm wrong in investing in a little peace of mind.
The way I see it, you're gambling either way. As you and so many others have put it, if you buy the warranty, you're placing a $2400 bet against yourself that the car will require enough repairs to cover the cost. If you don't take the warranty, you're still rolling the dice and hoping that any repairs required don't exceed the $2400 (or $3k with interest) price of the warranty. As I mentioned before, you can DIY to keep the repair cost under $2400, but for me, the 2-3 hours of quality time I get to spend with my family is worth more than the money saved on a 2-3 hour DIY repair in the garage.
YMMV.
