I have a 2003 Saab 9-5. The car looks like this:
I would like to be able to carry a small-ish bicycle now on regular occasions but unfortunately it cannot fit inside the car unless I take off one of the wheels. As you can see the car has no roof rack or bars and it's not clear to me what you could attach to the back of the car to be able to carry a bicycle.
What is a cheap and effective way to fit the car to make it easy to carry a bicycle? I don't really know the first thing about this so please spell out exactly what I would need to buy if possible.
