I wouldn't buy a rack from BMW, whether for the hitch or the roof rails.

If I had to have a hitch rack for some reason, I would buy the Thule Doubletree or T2, or maybe the Saris. Nothing wrong with Yakima, I just don't know their models, but it would at least be a design like the Doubletree. A design that has the bicycle frame hanging free is suitable for kid's sidewalk bicycles, if you don't mind marking up your paint job. In other words, a last resort.

All of the above would only be an option if for example I had a convertible and no place to mount a roof rack.
