Why is gap insurance considered as a financial safety belt? Simply put, it keeps you from being financially ruined when disaster hits your car. For example you are in this situation, you bought a late-model car three months ago using a car loan with a regular car insurance. The car costs $30,000 and you have already made three payments of $900 each month. Then, disaster strikes. An electric post falls and slams down on your car. The car was flattened to half its height.
