If you will be financing your vehicle and not using at least a 25% down payment, then you definitely want to learn the benefits of GAP insurance.
In a nut shell, GAP insurance will settle the difference between your insurance companies payment and what is actually owed to the lender in the event your vehicle is totaled out in an accident or stolen and not recovered. This can equal thousands of dollars that you'd have to pay without this coverage.
If you are not familiar with GAP insurance, please do yourself a favor and learn more about GAP Insurance once you are done reading the car buying guide.
