Okay, so your info-block reads that your M3 is in Production.
The first thing you should do is find a downloadable owner's manual and read it from front-to-back, twice. You will learn all sorts of things you need to know, and all sorts of things you will never need to know. But chances are, almost all answers to your questions are either in the manual, or have been discussed one-hundred billion times on this particular forum.
