It's difficult to pack the car for vacation if it is already full. Think of these reasons to clean out the car. Small items kept in the space underneath the rear windshield, such as compact discs, cassette tapes, toys or books could be come dangerous projectiles when you stop the car suddenly. Carrying around a rolling storage room can hurt you financially.
Cluttered cars invite thieves.
If you have an emergency, like a flat tire and need to pull to the side of the road, its frustrating enough without having to empty all the junk out of the truck to find what you need - the jack, spare tire, road flares or emergency signs. It's embarrassing, a waste of time when you really need the time, and absolutely unnecessary. It's a small job. Cleaning out the car, verses cleaning out the house, takes only a few minutes. All you need is a garbage bag.
