I’m a firm believer of buying a extended warranty. With all of the electronics they have now days and they are very expensive to repair. I had to have a air conditioning door control motor replaced and the whole dash had to be removed for the repair. The cost of the repair would have cost me $1,800.00 if I had not purchased an extended warranty. I think the GM warranty is the best and shop around on line for the best deal. Not all dealers sell them for the same price, some sell them for $50.00 over their cost.
