My car did not come with a wing from the factory, but a previous owner had added it on. It blocks an already restricted rear view, makes the trunk too heavy to stay up, collects dust and a whole list of negatives. On the other hand, the kids just love it. They go ape over that silly wing. I love seeing them get all excited about it. Makes it almost worthwhile. Besides my wife uses it to wrap Christmas presents on every year. What would she do without the Pantera wing on which to wrap presents?? So for now, thge wing stays. At least until after I have grand kids and see if they go ape over it too.
