I have used bike racks on a number of different vehicles and have usually found the factory option to always be more expensive (sometimes more than double), but far more suited for the task than any of the aftermarket versions. The reason is that the aftermarket units are generally a compromise to accommodate several makes and models, while the factory(dealer) options were specifically designed for the vehicle. The reduced production volume of a model specific rack, of course, will drive up the cost/price. My 2cents.
