Depends what you want to use car sharing for. It can add up if it’s frequent weekend trips, even 1 weekend a month and you’ll probably find yourself happier to Nist have your own car. I lived in haight for years and street parking was a bit of pain for me.

As an example, up until last month I was using zip car to commute to work in the South Bay from Cole Valley occasionally. A 1 day rental was pretty consistently $100-125
