The least expensive method to ship your car is typically using an open carrier. Open carriers are the most common and cost-effective option for auto transport. They are widely available, and their capacity to transport multiple vehicles at once helps to reduce costs per vehicle.

Here are a few reasons why open carriers are usually less expensive:

1. Higher Capacity: Open carriers can accommodate more vehicles compared to enclosed carriers, allowing the transportation costs to be distributed among multiple vehicles, thus reducing the individual cost per vehicle.

2. Lower Operating Costs: Open carriers have lower operating costs compared to enclosed carriers. They are less expensive to purchase and maintain, resulting in lower transportation fees for customers.

3. Greater Availability: Open carriers are more readily available since they are the standard choice for auto transport. The higher availability of open carriers means that you have a wider selection of carriers to choose from, which can help you find more competitive pricing.

It's important to note that while open carriers are generally more affordable, they do not offer the same level of protection and security as enclosed carriers. If your vehicle has special requirements or you prefer added protection, an enclosed carrier might be a more suitable option, despite the higher cost.

To get the most accurate and competitive pricing for shipping your car, it's recommended to reach out to multiple auto transport companies, provide them with the necessary details (such as the origin, destination, and vehicle information), and request quotes. Comparing the quotes will help you identify the least expensive option that meets your transportation needs.
