GRAB IT! Our 4yr 48Mo Powertrain, a/c, electrical, a/c service contract (s/c) was $3,750 from AUL in Napa, CA. Worth it’s weight 150%.
It covered our air suspension and pump. The GMC Dlr offers a lifetime warranty on some oem parts they install. So far that would be the radiator & alternator the s/c replaced. Lifetime warr at dlr on a 10 year old truck with the s/c paying for it is good.
