Do you have an extended warranty on your car? I'm looking to get one on mine.?

My car has about 96,000 on it now. I don't have any problems with it right now, but would like to get a warranty on it to be on the safe side. I toyed with the ideal of trading it in for a car with less miles on it, but I only have two years left of the loan. The ideal of not having a car payment just seems much to attractive. Plus I know my car is dependable. What company would be good for a car with that kind of miles, and what ones should I stay away from?
