The comprehensive (bumper to bumper) is 3/36 the powertrain is 5/100. I think as a
consumer that it is always a good idea to purchase an extended warranty if you plan on keeping your car past the 3/36. if I were to lease the car and was not keeping it longer I would pass. My dealership offers discounted warranties on ALL GM products through this website
