Yeah, I want to chime in. Not only is having a car expensive, but it even when you can afford it, it does not make anything easier. You don't necessarily get parking spaces closer to your destination than where the bus stop is. Often you're walking farther to and from your spot, than where the bus/MUNI/BART/cab would drop you off.
Also, in a city, you're always having to move your car even when you don't need to drive it anywhere for street cleaning days. If you're lucky enough to have a garage for it, it will be hundreds of dollars a month. You're already cutting it pretty close with your budget. Really, really, really don't bring it.
Otherwise, I think your plan sounds amazing, and I hope you post here from time to time about your experiences.
