The two important car transport trailers are open carrier and enclosed carrier. Open carrier is the most popular and least expensive type of auto shipping. Your car will be transported on an eight car hauler, the same type of trucks used to deliver new cars. These trucks are 75-80 feet long and almost 14 feet high. They are difficult to maneuver and are limited to major roads that are free of low hanging trees and low clearance bridges. Make sure you keep in mind when directing the truck to the pick-up location. If you want that your car should be clean then transport your car in an enclosed car transport trailer. Enclosed trailers protect your car from all road hazards and weather. This is the most expensive option in enclosed trailers. The following features are available at additional cost: lift gates for safe horizontal loading, and winches for inoperable vehicles. This type is suitable for costly or exotic cars. Some other famous enclosed trailer options are six-car enclosed trailers, four car enclosed trailers, and two-car non-stacking enclosed trailers.
