I have the Saris Thelma hitch rack. It is easy to use and I am short, so on top of the car is not an option. I don't leave my bike on the rack, though, to go shopping, etc. It's just to transport it to rides, vacations, etc. I can fit it inside of my car if I put the back seat down, but my husband's bike doesn't fit in my car. If I have to leave the bike, I put it in the car.
