A closed car trailer or auto carrier is a vehicle that has a covered freight area. It is most commonly used when shipping an expensive or classic car that you wish to protect. If your car will be traveling cross-country and going through some dry and desert territory, you may consider using a closed trailer to protect it from wind blown sand and heat. If the vehicle is not being shipped through extreme climates, consider using an open trailer.

Advantages:
The car is well protected from the elements of nature.
Disadvantages:
Closed auto trailers and car carriers cost more. Remember, price is determined by the weight of the vehicle being shipped.

Tips: Remove all valuables from the car, leave as little gas as possible in the gas tank for weight and safety purposes, and always insure your car, just in case it gets damaged.
