Does anyone have experience with using a rear-mounted bike rack (see attached) on their 2013 or later MKZ? I'm concerned that the black plastic or composite material on the upper third of the trunk-lid will get cracked due to weight and/or scratched by the clips used to attach the top portion of the rack. The one photographed is listed as a match for the make & model, but In my mind I need a little more assurance.
I don't have a trailer hitch, and would prefer not to install one just to carry around my bike. My car has the pano roof so top mount racks are out of the question.
Any info is appreciated!
