Parking was murder at my alma mater. Students, undergrads in particular, were highly discouraged from having cars. And in Boston/Cambridge, you don't really need a car anyway.
Each of the two student family housing buildings has its own parking. The one I lived in actually had a garage.
All other students living on campus shared one parking lot that was wayyyy off at the far end of west campus. This was especially bad if you happened to live on east campus. Most east-campus residents parked along Memorial Drive; unfortunately that is a snow emergency route, strictly enforced, so whenever it snowed everyone had to move their cars into the lot.
Half the spots were for grad students, the other half for undergrads. Each undergrad dorm was allocated a handful of spots, which were given out by lottery. Grad students could pretty much have a spot for the asking. There were always fewer grad students with cars than spots, but the extra spots were not reallocated to undergrads.
There are separate commuter lots for those living off-campus, including off-campus fraternity and sorority houses. These are pretty convenient to campus (more so than the resident parking!).
Edit: Forgot to answer how much parking costs. It used to be $10/semester, then it suddenly got jacked up to $300/year.
That's for residents; I'm not sure what commuters paid. Parking tickets usually ran around $10, but if you didn't pay, you couldn't register or receive your diploma.
One year, the parking office forgot to put the little R on the residential parking stickers (commuter student stickers were identical, but no R). An overzealous campus cop ran around the residential parking lot one afternoon, ticketing every car in the lot for not having a resident parking sticker. Did I mention the lot was keycard controlled, so you couldn't even get your car in the lot if you weren't entitled to park there??
A couple of people I know fought the ticket and won, but a lot of people just paid. $10/ticket x 150 cars = a lot of donuts
