I just bought a car and my girlfriend has a similar car. We don't really want to scuff up the cars with the types of racks that use pressure points on the trunk.
Neither car currently has a hitch at the moment. Neither car has a roof rack nor the ability to put one on as far as I know.
What are the pros/cons of installing hitches and using a hitch rack vs. buying one rear rack and switching it between cars as needed?
Edit:
We went to REI today and picked up the Yakima SuperJoe 2. After trying to fit it on my car, there's no way it's going to work because the inside bike will rub on the car and not sit correctly because of the pedal. We are going to go back tomorrow and grab the Yakima SuperJoe 3 because it should give us more distance from the car.
