DING! DING! DING! WE HAVE A WINNAH!
The first thing that hit me was that the angled piece on the cheap hitch attaches to the subframe; that subframe is designed as a semi-free floating piece of the suspension. The rest of that hitch ties to the existing bumper frame. With the vehicle at rest, it doesn't make any difference, but I would imagine it would transfer some road noise to the frame (minor annoyance) but if you were driving it down a rough road, there would be a lot of torsion being placed on that bar, and torque applied to a now-weakened subframe (because of the hole drilled in it) and bumper frame. I don't think I'd be using that hitch, but if you're ok with it... It's your car, and your 600 lb motorcycle hanging off the rear end.

who, after seeing the ~$500 price tag at ECS Tuning is pleased as punch to have bought an X5 that already had the factory hitch on it.
