My theory is in the long run if you do not buy any extended warranty you will save money (since obviously there is profit built into the insurance). I mean never buy an extended warranty on anything period. By the way I have a 2000 Bonneville SE that has about 75,000 miles on it and is about 7 years old and the only thing I've paid to replace is one window motor. I also have a 2004 GXP that I love and is still under the original warranty. At about 32000 miles the water pump was leaking, a window motor was broken, and the dealer gave me new rotors (since the first set wore prematurly due to sticky calipers and having been recut at about 14000 miles ---- seems lots of people had this problem). Luckily this was still under the original warranty. I still won't purcahse an extended warranty. I also have 2 monte carlos....a 2003 and a 1998 and neither have had repairs that have exceeded the cost of an extended warranty. The 1998 is getting close...but its 9 years old and wouldn't be covered anymore in any case.
