I just got a '99 Eldorado with 15k on it. The factory extended warranty expired in November 2004 so I cannot get GMPP. It seems that the only one I might be able to get is through AAA. Does anyone know if this is a good plan? Can anyone who has it comment on the claims process and other aspects? I'd hate to buy it only to find out that it only covers parts that don't break (like the engine).
