Perfectly good option. Options vary dependng on miles on your car. There are options @ {30k, another at {40k, and another just before your factory warranty expires @ {50k. Each milestone reduces the time and availability of more miles though, so keep in mind that what is available now for extending coverage to 114k miles will not be available to you. The longest coverage available just before the 50k mark will only cover you out to 98k. Just a heads up.
Best of luck no matter what you do!
