 trailer, a little tiny aluminum trailer, because all I have to do is drop the ramps, drive the car off, and go. I don't have to disconnect the lighting connector, the brake connector. Some states require brakes on the car if it's being flat-toed, and if you pull through a state and a state trooper pulls up next to you and looks at your trailer hitch as you're driving down the interstate and they see you've got a tow bar hooked up and you've got one lighting connector and no brake wire on there,
