Well I do not know about all the aftermarket hitches but I do know after extensive research that none of them had a truly concealed hitch especially "hidden hitch" and a system hitch which was not sold ala cart, all had extra charges to complete the system. I have an X5 and a brand new X3 and me being a very picky BMW owner will not put on a product that takes away from the look of my BIMMER i.e. big square tube coming out the rear. Phantomhitchesdotcom provided me and my wife a complete tow system and excellent service.

Install was the same as after market brands(1.5hrs) but my hitch had a superior electronic cambus unit which is able to read my SAV advanced electrical system and it is HIDDEN (truly) from view when not in use. The price is more than the aftermarket but nearly half the cost of the OEM. Westfalia is the OEM brand which provides BMW its hitches but for the $1400-$1600 price tag they are truly smokin crack ! Check out the site(PHANTOMHITCHES.COM) if your looking for the IDEAL tow solution. You will not be disappointed, I was'nt.

Cheers
