I agree with midwesterner. You're betting $900 that you WILL incur enough damage to exceed the amount you pay for this "warranty". Unless you're overly hard on your vehicle, drive on roads with horrible potholes and other road hazards, park close to other cars who ding your doors, I'd cancel this within the 30 day period.
We purchased a new 2015 RX 350 a month ago and of course we were "offered" the extended service plan, with the warnings of how expensive some major components are to fix or replace. We said thanks anyway.
