On the GT I remove the bumper and the new "tow hooks" are welded along the bumper support boxes. They are done so that the bumper can be attached normally, just removed for towing so that the tow bar can be attached with pins.
Cost about $500 I think for installation and the tow bar.
I use tow lights that wind from the rear hatch out a driver's window, down under the hood and out the front lower grill (I have wire mesh with a cutout for the plug to feed out thru.
About 15 minutes to pull the bumper, feed the light wiring and pin in the tow bar. The lights hang out the back, held in by the hatch closing.
