I almost went to med school; went to law school instead (and became an intellectual property attorney). some days I think that I made the right decision, others I don't.
The grass is always greener, etc.
To the OP: med school is a monumental olibgation - an obligation that requires a lot of time (~10 years) and, unfortunately, an absurd amount of money (some schools are apparently now charging 70k a year in base med school tuitition?).
whether or not you should be buying a M3 should really be the last thing on your radar.
