Car storage units can be a major pain if you are not careful as you shop around for them. Indeed, if you end up renting a unit that is not going to keep your car safe, then you are going to have to cope with a world of pain when you come back to retrieve it. You might have some dents that you didn't have before, or it might get stolen entirely. Not all facilities are like this, though; hardly the case at all. Just be sure that when you are calling around for your car storage units, you are keeping a close eye on security features and those sorts of things.
