Buying an extended warranty is like buying insurance. You're betting that something bad will happen, and the company selling you the warranty or insurance policy is betting that it won't. I don't buy extended warranties and have yet to regret it.
It seems to me that most problems should be resolved before the 3 year 36,000 mile warranty expires, so I am going to gamble that my 2003 will be a non-lemon after that.
