Most dealerships are the middleman when it comes to providing you with extended warranty. They often purchase the same warranty through a company such as National Dealers Warranty. They then charge you a significantly higher rate in order for them to make more money. Dealerships are excellent for providing you the actual vehicle. However they do not always offer you the best price on extended warranty. National Dealers Warranty will provide you the opportunity to go to the source for extended warranty and thus will save you money.
