it came with 7 miles and on the way back i was goin about 120 mph in 6th gear at about 3.5k -4k rpm uhhh am i ****ing my car up? cause iheard only thing that matters during break in is the rpm. i sumtimes overrevved at low speeds (20-40) and went up to 5k or 6k. can sum1 give me proper break in procedure? my salesmen didnt really go over stuff. theres about 142 miles on the car now.

Break in: There are generally 2 acceptted methods:
The hard break in: It's alot like you're already doing. Drive the **** out of it from the beginning. Its generally thought and I've seen some tests that are done as scientifically as possible using 2 identical cars (as identical as possible) that a hard break in will give you more power but with worse mileage, wear etc.
The break in everyone knows: Generally the RPMs differ but usually keep it under 3/4 K for a specified number of miles. I don't know what that is for an M3, but for my father's 911 Turbo it was under 4grande for 2000 miles (which really sucked). You also don't want o cruise at the same RPM for long periods. You want to vary the RPM to give the engine maximum flexibility over and through out the rev range. If you truly care about your car this is the way to do it. I also like to "stretch" the motor starting about 1/2 way through break-in which means occasionally going past the rev limit.
When I broke in my ZHP I kept it under 3 more or less for 1200 miles, and then I added another 400 of keeping it under 5.
Break in allows oil to get into every little crevice in the motor as well as letting the cylinder etc self polish. The longevity of your motor is greatly increased.

DBX,
It's funny how some without M3's say the break in period is BS... You need to take it easy for the first few hundred miles... You will gradually feel a difference, and you can hear a difference too. Keep the RPM's varied to create the proper seals for the bearings. You will find that most M3 owners that rip on their car straight off the lot will have issues with the motor burning excessive amounts of oil. I have 12K on my car and I followed the Break-In procedures pretty closely... But I didn't baby the car either. My car has not burned any oil, and I drive it hard. All I'm saying is that you need to let your engine loosen up a little... Same with your differential, but that will be broken in without much thought. Think about it, 1,200 miles of easy driving, varying RPM's and then you can enjoy 100K plus miles of fun... Take it up to 7,900 RPM all you want after that.
PM me if you would like more detailed information about the Break-In procedure. I have seen a total of five E46 M3's go through the 1,200 mile Break-in. Each one was done slightly differently and the results start to show at around 5K miles.
