I believe extended warranties should be added to the new "Total Value Promise". I am impressed, a little, with the 4yr/50k warranties (5yr/60k would be better) on Cadillac and Saab. Supposedly Buick and Hummer will get this too, but why not the rest of the brands (Chevy/Pontiac/GMC/Saturn). With extended warranties I believe people will take GM on their TOTAL Value Promise. At the least, GM could offer extended power train protection on all their vehicles.
