Why do I need GAP Insurance on my New Vehicle 

I bought Gap. New car. Cost me 325 dollars for the life of the car loan. Was a no brainer. My car cost 20,000 dollars on the lot and 17,500 the second I drove it off the lot so that 325 would save me 2500 if something were to happen Edit. I got gap thur my car insurance company. It was cheeper than the dealer and covered the car for the full value.
