Great idea—knowing ahead of time what you want to buy helps you stick to a budget and leave the car dealership with more money in your hands.
All new GMC vehicles come with a standard 3-year/36,000-mile limited warranty. The extended warranty covers you for 5 years/60,000 miles. That means that the extended warranty only gives you a couple more years of coverage than the standard—so it might not be worth the extra cost. And remember, a warranty only covers parts that malfunction under normal use. It won’t cover damages due to accidents, acts of God, or improper maintenance.
