I am carfree and have been for all of my 26 years. However, I don't believe this is quite the same as having one and then getting rid of it. The question you need to ask yourself is how much do you use your car right now? As the others have said, hang onto it for the time being. If you find it just sitting there taking up space in a few months time, then think about getting rid of it if that's what you want to do.

And don't always rely on buses. In Brisbane, 50% of all timetabled bus services fail to show up at all.
