I just bought an '05 LT Sedan, and didn't immediately purchase the extended warranty from the dealer. I was wondering if anyone here had any good or bad experiences with after market companies. AAA has one through Mercury Insurance, and then there are all of the web based companies. The dealer wanted ~2500 for the 84/100 (or the 72/100) either way it seemed like alot. The AAA one is 2000 for 84/100, and includes the tire damage, which the GM one didn't even cover. Any inputs will be greatly appreciated.
