Why don't you just save your money and not mod the 325. Then you can save your money for an m3 later in life. Trust me. I'm 19 and in college and pay for everything myself. I had a 2006 330xi, I dumped a ton of money into a car (bumpers, wheels, coilovers, maintence items, etc) I shouldn't have and was dead set on buying an m3 right out of college. Things change. I bought a 2011 135 two weeks ago and realized dumping a ton of money into that car was the dumbest thing I could've done in my life so far, especially a 330 where gains are minimal. So I bought my 135 because in a couple years I'll have a town house and my soon to be fiancé and bills to take care of and don't want to be stuck with a big payment on an m3. Now a couple years down the road after I graduate sure I won't mind but not fresh out of school. I'm not trying to give you a life's lesson man but my advice to you is save your money because dumping money into a 325 is stupid. Not saying the 325 is a bad car, I'm just saying you won't get your moneys worth. If you really want the m3 save every cent you have you'll be good out of college for a nice m3
