<prompt> Human: Whats the general consensus on buying extended warranties for a car that take over once the manufacturers warranty runs out?I have a 2009 Jaguar XF with 40k miles on it and about 6 months left on the mfg warranty... I plan on keeping it for at least 5 years. Is it worth it to buy an additional 5 year warranty?  <response>: The expected monetary value is strictly negative. That is how the warranty company makes money.However, its a risk appetite question.If you had a significant problem with this car, could you afford to fix it? That is to say, if there is a 110 chance that youd need to spend 8x the cost of the warranty, would you be ok? The numbers arent exactly like that, but they represent the warranty companys business model.Basically, youre paying a premium for the peace of mind with a less-likely event.
