Is the car able to be towed per the owner's manual? You could also check with the Motorhome towing guide for 2003 autos to find if the car is able to be towed and what equipment maybe needed to allow for towing.
I also would certainly recommend if it is towed you use a braking system such as Brake Buddy or similar.
