Determining the price of car transport varies based on if it is on an open trailer or an enclosed trailer. On an enclosed auto transport, the price is typically based on the actual miles driven with your vehicle. Based on fuel that rate per mile will change, and based on the distance the rate per mile will come down. Most enclosed trucks have a minimum, so even if you are moving your car 10 minutes on an enclosed trailer, there will be a minimum fee depending on the company. On an open car transport the rate is calculated totally differently. Open trailer rates are more based on a given route. For example, the rate Texas to Florida can often be less expensive that from Florida to Texas. Things like, fuel, supply & demand and availability are all factors that are considered when going on an open transport. As long as you have a good carrier and you them what you are wanting to achieve you should not have a problem despite who you go with.
