I went from 335 to m3 to 335. you will be ok but guess what I am doing now back to m3.
the m3 is funner and cooler and better period, yes even for daily driving. the 335 is NOT better for daily driving I don't care who says it is. but there is nothing wrong with it.
Best thing to do is get rid of the m3, drive a 4 cycle civic or something for a couple weeks then get the 335. It will feel better then you even remmber the M3.
