Not sure which 2005 BMW X5 Trailer Hitches are right for you? We have over 135 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Jeffrey I from Pittsburgh, PA said, "I've intalled hitches on other vehicles in under 30 minutes. I was unable to install this on my X5. The instructions claim that it would take a professional 1 hour to install. I found this to be not even remotely close. The bumper had to be removed which is well above my pay grade. I had to take it to a professional who had to redrill holes in the bumper brackets."
