Anything major should have broken already which leaves nuisance things which won't add up to the cost of the coverage.
Remember, they don't sell extended warranties because they plan to pay out - they sell them because the numbers show it's easy money. Sure, there's always that friend of a cousin's neighbor whose engine exploded for no reason one month after the factory warranty ran out, but that's the exception to the rule.
As others have said - if you have the 2100 bucks to buy the warranty, put it in an
online savings account instead. If you need it you can still get at it fairly easily, and if you don't need it (you probably won't) you'll have upwards of 600 extra dollars waiting for you after the three years. Better still, if you don't already have a savings account going, this is your chance to start. Open it with 2100 and then throw in an extra 10 bucks a week or something - it all adds up. If you were going to finance your extended warranty (even worse idea), make the payments to yourself instead.
