You absolutely do not need a car. I would try and allot my funds so that I can live closer to work (though I would avoid Lawrenceville as being too pricey for no very good reason. It has been my experience that under 25's get crushed when buying automobile insurance unless you can pay cash and buy only liability without collision coverage, a risky idea in this city. Parking is also expensive if driving to work daily, but you might be entitled to free parking.
