street parking is your only option. most of the apartment streets have 2 hour parking on weekdays. all of them have street cleaning either thursday or friday at 8-12 or something so you have to move it before that.
but its VERY hard to find spaces near the dorms. south of wilshire is a bit easier to find, but thats quite a walk from the dorms.
if you plan on actually using you car a good amount, i wouldnt recommend bringing it at all. it would be a massive headache to find a space every time you leave and come back, and then having to walk all the way back up to the dorms from where you parked (which will usually not be close to the dorms).
you can check facebook/craigslist/etc to see if any apartment people are selling their spaces. usually they sell them for $100-150 a month.
