Help with finding a compatible college in MA.?

Law isn't a major, and most liberal arts colleges don't offer business. You should be looking at state universities; try UMass Boston, Dartmouth, or Lowell (Amherst is more selective). While most schools won't let you park on campus your first year, you can pay to park off campus (although you're far more likely to drop/fail out if you keep leaving school, which is why they usually don't let freshman bring cars).
