Sucker for a lemon

My car died on me the other week. It straight up and quit on me. All power cut out for about 10 seconds before coming back on. Now my car is in the shop and the mechanic is telling me that the warranty company won't cover the repair(thus far). He still hasn't found the route of the problem which means that the bill could get even higher. I'm hoping that it gets high enough to total the car. My insurance would waive any further payments on that car and allow me to finance a new car. I hope they total my car out before the repair bill gets too high but not high enough to total it. I seriously want to take this car back to the dealer and set it ablaze in the black of night. That would surely bring me some satisfaction.
