There are of course variables, but these numbers should put you in the 'Ball Park'. It is almost always better if at all possible to get the car running and driving. It will make your life easier finding a transport company to pick it up, and some shippers won't touch cars that they can't drive onto the ship. If a car has been in storage a long time, ask the seller if he could recommend a local mechanic who could come out, put some fresh petrol in the car, charge the battery and get it going before the trucker picks it up. There is one very important difference in trucking services that we feel you should be aware of.
Some companies own and operate their own fleet of trucks.
Although these companies are typically more expensive, they offer many advantages over those that don't. Most important is that they accept full liability for your vehicle whilst it is in their possession. Some companies simply act like 'travel agents'. They arrange 'passage' for your car on a transporter that is going in the direction of where you want your car to end up. This sometimes can mean that your car is loaded and off-loaded several times onto different transporters to get it where you want it to go.
