I second the motion for installing the hitch. I wanted an EASY to use rack for just one bike. I searched and searched and we found a platform rack at Sears (who would have thought) on line. My husband put a hitch on my BMW 325xi and the rack is so easy to use, even a mechanically challenged person like me has no issues. I thought my bike would fall off, but it's secure and I have driven on the freeway with it twice. Yes, the thing is on all of the time, but it folds up flat against the back of the car. I am short and could never do a roof rack, either. It comes in a 2 bike model.
