You should do a search on this site under "extended warranty." I think there was some discussion around this recently, including what to look out for. As Artic and Ovr pointed out, you might be able to put off this decision and shouldn't feel rushed into it. Extended warranties are often a good idea if the long term reliabilty of a car is uncertain (concerns about Mazda trannies have recently come to light), but your own comfort level is also a consideration.
