Extended warranty?

Just wondering how many people purchased the extended warranty and if it’s worth it. My dealer offers the 5 year for around 700. My main concern is how much is really covered under the warranty. I’ve read a lot of negative warranty rants seems like they are always trying to find a way not to cover the claim. So I guess to sum it up. Is the extended warranty worth purchasing? my factory warranty expires at the end of the month so I was looking for some input from anyone that has purchased it
