Hi, Just bought a 04 Subirban 4x4, 6.0 L 2500 with 85000 miles. It is in great shape but I can buy an extended warranty for about $ 2000 to cover another 25000 miles or 2 years. This is a second vehicle so I wont use up all the miles in two years I expect - I know that if it has to get anything like tranny work etc. the $ 2000 doesn't go far at the shop. Anyone got an opinion on this. Warranty is through GM.
