Enclosed Auto Transport Carriers also range in size and capacity from small 1-3 car trailers typically pulled by full-size heavy-duty trucks to large 6 car ramp load trailers and top of the line 6 car horizontal liftgate trailers both pulled by a semi. Since all of these carriers are completely enclosed trailers, the vehicles are not exposed to any weather, dirt, debris or rocks from the road conditions while in transit. They cannot be seen by curious or malicious people along the way. Enclosed auto transporters are highly recommended for classics, muscle cars, resto-mods, vintage, luxury, exotics or any vehicles with low ground clearance. Anything that requires extra piece of mind. Enclosed auto shipping costs more than open auto transport due to the added protection and exceptional value but is well worth it.
