This is always such a difficult question - theoretically, most schools (aside from JHU, WashU and Columbia) are NOT really number ******. That is, a lot of students are accepted with MCATs below, at, or slightly above 30 and GPAs ranging from 3.4ish - 4.0. If you have something else in your application to set you apart - extensive work experience, volunteerism up the whazoo, stellar recs, president/dictator of a small country, etc. - you'll be looked at regardless. Also, a lot of schools really do play the "fit" card, and tend to accept those students who are going to contribute to their institution, etc. (Which makes sense, I guess!)
Given my application experience and my friends' experiences, I would say that Yale, Harvard, Penn, Cornell, NYU, Stanford, Mount Sinai, Albert Einstein, BU, SUNYs (if in state) and Case tended to interview and accept people with perfectly-fine-but-not-too-stellar MCATs (at or slightly above 30), stellar GPAs (> 3.8) and a lot of work experience. Since I'm a postbacc student, and my sample size is about 10, take all of this with a grain of salt! Most of the these schools (in particular Harvard, Penn, Yale, Stanford) turn down fabulous on-paper applicants and accept students who had that special something in their application - and I'm not talking numbers.
