Not to sure, it was second hand and came from the same model. Just cannot see where it would mount under the car. I'm guessing I will need to cut the bumper.
I agre with the snooper, the spacers on the drop plate suggest the rear valance is double skinned and that is where that part goes and the 2 outriggers are certainly boot floor supports.
Most cars today with their all encompassing rear bumpers do need cut and sometimes there is a marked outline of a weakened 'letterbox' on the bumper inner surface.
There probably won't be any marked 'drill here' points on the car, just a case of careful measurements to ensure centre.
Look to see if there are any blanking plugs in the boot floor and valance. I think modern tow bars are supposed to use holes and fittings already in the car as designed by the car manufacturer as being suitable for the stresses generated when towing (within the limits of the designed towing capacity of the car which is sometimes less than the limits in LAW)
this is the Anker tow bar I think and if you go to their site you can down load the instructions from PDF ( its a file system)
BUmper has to be cut but not removed unless your keen
